“How much of this? How much of that? When is it too much and when is it too little?”
These questions seem to apply to nearly every “good” and “bad” quality/activity I can think of. The best answer I have found to them is: do enough or as little of everything I need to bring myself into a state of harmony—a state of visceral peace where my sense of time drops away, and so when I lay down at night, my molecules tell me I have done exactly what I needed to do.
Now due to the fact that I am a unique configuration of behaviors and preferences, there is no clearly defined recipe that will bring me into harmony. That being the case, only one approach seems to make sense:
Experiment and adjust, experiment and adjust.
