One thing that I used to always wish for was to reach some sort of equilibrium in life. Namely, I wanted to reach a point where I never had to worry about my career again, or got down to the right weight or got in "good enough" shape or had enough money or had a daily routine that I always stuck by. I've come to realize that this is a fairly self-defeating desire.
While I'm all in favor of systems, I think we have to expect that things will break from time to time. This is especially true when we travel. Sometimes, our schedule will go haywire. It will take time to get back on top of things. Sometimes we'll eat terribly for a few days, or stop working out for a few weeks. Sometimes our career might be exciting, others it might feel pointless.
I've come to accept that we need to look at this from a more macro perspective. There will always be ebbs and flows in life. We should never plan on "getting there" because there is no "there" to get. We can always do better than we are now. Even Warren Buffet could make more money. Hell, Jeff Bezos has more than him.
The key is to try to build systems and align your life so that 1) you will be successful, although the "what" and "how" isn't necessary to answer and 2) will enjoy the path. Finally, 3) you need to be able to both forgive yourself for deviating from time to time and understand that you will, because no one and no system is ever perfect.
That is the type of equilibrium, if it can even be called that, that we should be striving for.
