+1 on health as well. I worked at SpaceX earlier in my career. Others wrote about how having just a career for meaning in your life can have downsides and I wholeheartedly agree. Let me tell you that job gave me meaning, novelty everyday, launching rockets into space, non work friends always asking questions. The downside for me was I absolutely neglected my health because work was more meaningful than basically anything else, relationships, fitness, family. Focusing on fitness, when I left the company I realized how terrible my health situation was. Lots of late nights, lunch at my desk, and lack of physical activity took a huge toll. Getting to a healthier state fixed all the usual stuff, but also unexpectedly gave me mental happiness and has made me a better data scientist as well. I wrote a blog post detailing out why desk nerds should very much consider taking on healthy habits, and it brings me so much joy to see others here have seen similar results as well. https://ravinkumar.com/WhyFitness.html https://ravinkumar.com/WhyFitness.html
