How much time, by the clock, have you spent trying to think of different things you could be doing?
I haven't committed any numbers to memory, but my time is mostly divided between trying to think my way to doing something and trying to avoid drowning in frustration by wasting time on the internet. Just judging by how today has gone so far, it seems to be roughly 1:2 or 1:3 in favor of wasting time. I did briefly turn off the internet at one point, and that seemed to help some, although I still didn't manage to make good use of that time.
Or maybe you should be trying to draw on other things that could make you happier, like hanging out with friends.
I have no such opportunities of which I am aware.
I recommend poking around in your mind to find out what's actually in your mind, especially when you're considering taking action. I've found it helpful to find out what's going on before trying to make changes.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
