Optimizing for energy

In the world of startups and investing and ideas, things are always chaotic and fluid, and as such a key skill is to somehow cut through the noise and find focus.  That's on a micro level, like what do I do for the next five minutes, and on the macro level, like am I (or are we) heading in the right direction? This may be true in other fields, but I find it to be especially true on the investing side, where situations are undefined, and there are infinity ideas and directions to explore.  On the operating side, things are slightly more bounded, but there are always large questions about direction and focus. So I find myself spending a lot of personal time working on my own mindstate, and trying to find ways to help with this challenge.  One thing I have tried this year is to use a Volt Planner, which helps you structure goals on a weekly, monthly and yearly basis.  I have found this to be incredibly useful, and I can write more that later.  One immediate observation from using the Volt Planner is that I emerge from each session (on Monday each week) feeling a rush of energy, paired with an increased sense of focus.  It's really nice. And that energy is really the important thing.  It's the foundation for all of the moments and decisions that happen, all day every day.  The more of it you have, the better.  It's foundational. So a little more broadly, I've been thinking about how important it is to optimize for energy in life.  I think that is some combination of exercise, diet, sleep, and writing.  Maybe that's obvious, and the first three are things that anyone would tell you are good for your health.  But "health", while obviously good and positive (especially compared to major injury or illness) is a little abstract, and for me at least, a little hard to motivate around on an everyday basis.  I suspect that will change as I get older. Energy is the foundation of doing anything, and it feels like there are compounding / exponential results to having more.  I am not saying I have figured out how to really rally myself behind this idea on a consistent basis (which is why I'm writing this), but I think it's worth figuring out which activities give you more energy and which suck it away.  Worth figuring out.
