It felt like pure pain.</p><p>I thought I would be able to handle it after years of lifting, but running is completely different than lifting.</p><p>Running is more of a mental sport than it is a physical sport.</p><p>When you lift you go hard for a minute or two and then take a break. With running you just keep going. There is no break until you cross the finish line.</p><p>I loved the mental challenge. It was exactly what I needed.</p><p>It felt like moving forward in space through running made it easier to move forward in life.</p><p>Prior to running I tried so many different habits to calm my mind. From lifting, reading, meditation, journaling etc.</p><p>It helped but only slightly.</p><p>But with running it was different.</p><p>I started to feel more confident and my social anxiety is nearly gone. Conversations just flow naturally and I don&#8217;t have to think about what to say next.</p><p>Since I started running, I&#8217;ve been able to climb out of that rut. I feel more focused and productive. My mind feels more sharp.</p><p>Most importantly, my stress has significantly diminished.</p><p>After running is when I feel the most relaxed. Especially during days when I get to run outside.</p><p>The mental toughness that you build from running expands into other areas too.</p><p>What was once stressful, is now something I know I can learn and figure out.</p><p>I was curious about the changes that were happening to my brain so I started to dive into the science behind it.</p><p>I came across <a href="https://www.youtube.com/watch?v=BHY0FxzoKZE&amp;t=617s&amp;pp=ygURZXhlcmNpc2UgdGVkIHRhbGs%3D">this ted talk</a> from Wendy Suzuki that made it all make sense.</p><p>The talk is about the benefits that exercise has on your brain. Specifically aerobic exercise (aka cardio).</p><p>What Wendy found was that a single workout can spike neurotransmitters like dopamine, serotonin and noradrenaline. This leads to improved mood and attention for up to two hours.</p><p>Over the long term, the anatomy of your brain changes over time through regular exercise.</p><p>Specifically in areas associated with memory, focus, long term planning and goal setting.</p><p>On top of all this, exercise protects your brain for neurogenerative diseases like Alzheimers.</p><p>Reaping all these benefits involves doing 30 minutes of aerobic exercise 3-4 times per week.</p><p>It doesn&#8217;t have to be running. It can be:</p><ul><li><p>Cycling</p></li><li><p>Swimming</p></li><li><p>Dancing</p></li><li><p>Hiking</p></li><li><p>Stair climbing</p></li><li><p>Sports</p></li></ul><p>Anything that gets your heart rate up.</p><p>I still lift. I love to. But running/aerobic exercise is my new non negotiable for me.</p><p>I hope whoever reads this finds this inspiring to take that first step. All it takes is 30 minutes 3-4 times per week.</p><p>Single habit can truly change your life which is what I experienced with running. I hope you experience that too.</p><p>That&#8217;s it for this week.</p><p>I&#8217;ll see you all next Saturday.</p><p>Cheers,</p><p>Ashvin</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://www.ashvinrj.com/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading!

effect.</p><p>The formula looks something like this:</p><p>small habits + consistency + time = compounding</p><p>What this means is that if you consistently stick to tiny habits, the effects of it begin to compound over the long term.</p><p>The best example to understand the power of compounding is looking at Warren Buffet.</p><p>If you look at his net worth, he made the most amount of money in the past 20 years.</p><p>The 100 billion dollars he made at 92 is the result of the investing he did when he was 14 and staying consistent with it.</p><div class="captioned-image-container"><figure><a

It can happen in other areas too.</p><p>Let&#8217;s say you start to exercise consistently. You&#8217;ll notice that your mood will be better. You&#8217;re able to focus more. You&#8217;ll have a greater sex drive. You&#8217;ll sleep like a baby which will help you make better decisions the next day.</p><p>In the power of habit, Charles Duhigg calls this the keystone habit. One habit if done consistently, will improve other areas of your life.</p><p>There are a ton of books that sell millions of copies about this exact concept. But no one talks about how compounding can work against you.</p><p>Just like how good meaningless habits can compound over time, the same happens with negative habits.</p><p>An example is scrolling through social media.</p><p>You tell yourself &#8220;just 5 minutes&#8221; and next thing you know an hour has already passed.</p><p>If this happens every day for a year, you waste 365 hours.</p><p>And this is what most people miss.</p><p>You can do all the right things but nothing will change if you cancel it out with negative habits.</p><p>Let&#8217;s say you&#8217;re trying to lose weight. In order to do that you aim to eat 2,000 calories per day. That&#8217;s 14,000 calories per week.</p><p>You meal prep and workout each day.</p><p>Friday rolls around and you get invited for food and drinks.</p><p>You think to yourself: &#8220;I&#8217;ve been pretty consistent this week, I deserve this!&#8221;</p><p>So you let yourself have 3 beers (~450 calories) and a burger and fries (~1000 to 1500 calories).</p><p>All of sudden you added an additional 1000 calories to your day, undoing all the hard work you did earlier in the week.</p><p>It gets even worse when you repeat this Saturday night as well.</p><p>Next thing you know you&#8217;re actually gaining weight.</p><p>But Warren Buffet understands this concept very well.</p><p>During the internet bubble of 2001, he was ridiculed for not investing into internet startups.</p><p>Warren didn&#8217;t let greed push him to invest in an industry he didn&#8217;t understand. He stuck with his old boring businesses.</p><p>When the bubble crashed, people lost a lot of money. But not Warren. He was able to keep reinvesting his profits and keep compounding.</p><p>He would&#8217;ve undone years of compounding had he invested in internet businesses.</p><p>The purpose of all this is to tell you to focus on removing the harmful habits rather than trying to adopt new ones.</p><p>Once you start doing that you automatically create space for more positive things in your life.</p><p>The thing is that removing negative habits is much harder than adopting positive ones, which is why no one talks about it.</p><p>Removing negative habits might involve:</p><ol><li><p>Finding a different friend group</p></li><li><p>Having to face uncomfortable emotions you&#8217;ve been masking</p></li></ol><p>When you try to eliminate negative habits things might get worse before it gets better. You might experience some sort of withdrawal before your mind and body recovers.</p><p>So here is the process of pruning out negative habits.</p><h3>How To Eliminate Negative Compounding</h3><p>The first step to change is by building awareness. So start by pulling out your journal and answer these two questions:</p><ol><li><p>What habits are preventing me from reaching my goals?</p></li><li><p>What can I do to eliminate these habits?</p></li></ol><p>The way to change is by shifting both your external and internal environment.</p><p>Change your external environment by increasing friction. This can look something like:</p><ul><li><p>Putting the game console back into the box after playing</p></li><li><p>Installing a website blocker on your computer</p></li><li><p>Removing sugar from your house</p></li></ul><p>That&#8217;s one piece of the puzzle. The other piece is your internal environment.</p><p>You&#8217;re still going to face uncomfortable emotions and cravings despite doing everything to change your external environment.</p><p>The best way to shift your internal environment is by keeping your mind occupied on something else.</p><p>You doing something stimulating. Find a new hobby that you want to learn more about. This can be:</p><ul><li><p>Reading new books</p></li><li><p>Going for a walk or run</p></li><li><p>Finding some creative work</p></li></ul><p>Keeping your mind and body engaged on something else reduces the chances of you giving into cravings.</p><p>That&#8217;s all for this week.</p><p>Would love to hear if you found this helpful.</p><p>I&#8217;ll see you next Saturday.</p><p>Cheers,</p><p>Ashvin</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://www.ashvinrj.com/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading!
