I've realized over the past couple weeks that one of my characteristics is not knowing how much work is enough. Sometimes, I paralyze myself into inactivity and passiveness, or find ways to be unproductive because I don't know how much time I should spend on a certain activity. At other times, I'll forgo sleep to do something I find interesting. All or nothing seems to be one of my mantras.
I'll take a simple example - studying.
I realized that I'm adverse to studying because I don't know how much studying qualifies as 'enough'. I'm a bad notetaker because I can't pick out the most important details and end up writing down too much. I like to read from the textbooks rather than from my own notes because I don't want to feel like I missed something.
