In addition to everything you said, there is also optimization issues of your goals. Eg, I like to think of myself as a very long term focused person (over the last 10 years, at least), but my ambitions outweigh my energy. So I have to balance in short term "play" as a way to destress and enable long term progress.

The fact that we're not robots in that sense makes this even more complicated as we can't just choose our long/short goals and stick to them, we often have to set them up within the context of what we can actually achieve.. which I think is often less than people think.
