Should I practice an activity, say drawing, programming, or even sport, in short day-sessions of one hour for example, or do it all at once in a week?
If I choose to do one hour a day, I might waste the concentration I just gained and I have to "boot", init, ... the activity everyday. Also, I may not be able to "surpass" myself, if such a thing exists, by spending a lot of time on the "problem" and eventually earning a revelation.
On the other hand, doing too much of the same activity may bore, tire me and I might be doing nothing after the first two hours.
Maybe neither of these two solutions are good, and both of them, or doing the second one with regular breaks to get the advantages of the first if there are advantages, ...
Maybe, the answer might be different whether I'm learning theory or applying it.
Ah, I'm so lost! What do you suggest?
