One reason is that, well, I want to live up to my parents' expectations and desires. It feels wrong to live off the charity of others (specifically, my parents) and refuse to look for a job, but I don't want to work and don't feel as though I am even capable of working. My father warns me that not working now will greatly reduce my future employment prospects, and that I'll eventually have to find work or starve after they retire and can no longer support me. (So I guess I'll starve, then?)

If I don't feel like doing something, I literally can't do it, and threats don't help very much; they just get processed as sunk costs, something to be endured rather than fought against. I also don't want to be the kind of person who does things he doesn't feel like doing - that way lies madness, drudgery, and wasting your life on things you don't care about.
