Perhaps "popular" startup culture doesn't focus on health as a priority and a reasonable temporary sacrifice? In reality, it's not temporary.<p>Taking care of your health is not lazy nor somehow less committed to your startup.<p>Taking care of your health and energy first is what makes the periods of extreme efforts productive instead of unproductive.<p>I was plenty unhealthy in my early 20's, it's almost glorified that we'll make up living later. While I am a deep believer in sacrifice, hard work, discipline, and focus... health, like time is difficult to make up.<p>I'm in this for the long haul, so I have to build my health to sustain me through it. If you can't be healthy now, juggling today's demands, it's hard to imagine it'll be easier in the future, when demands are even bigger and wider. One excuse often is simply replaced with another.<p>One thing I believe is crucial: include sustainable health and culture as a part of finding a startup's repeatable and scalable business model.<p>I've never been a guy who could go through the gym so I hacked my habits, and found something I could love doing (sports) early enough in the morning. I have never regretted one morning of getting up early, I am absolutely wired at 7:30 and fall into coding flow so easily.<p>Having now largely quit caffeine, greatly limiting my sugar intake except for fruits, etc, playing sports at 6 am a few times a week, managing my diet, and having a bit of Vitamin d and b12, my energy is absolutely through the roof.<p>Hacking my habits and myself has turned out to be a neat way for me to boost my energy and productivity, one habit at a time. Once I've explored and experimented with one new habit and got the hang of it, I add another thing.<p>This is coming from a life long night owl. I'd stay up 24-48 hours straight sometimes coding, and what I do now is more productive in more areas of my life. There's no comparison. Zero. Waking up early with a full and clear head of energy is 10x more productive than any late night coding I loved doing.<p>I'm not perfect at sticking with it for weeks on end, especially with a few late nights here and there. Every so often I reset the routine and I come out largely ahead from not doing it at all.<p>If startups are a temporary organization looking to find a repeatable and scalable business model, there's still a gap in sustainability, longevity and not burning people out, especially while working to validate through likely many iterations of an idea.
