My problem

My problem is that I have to be interested in and care about what I'm doing in order to do a good job and not save it for the last minute. For example, if I get an essay assignment that isn't interesting to me, I put it off until the last minute and don't do as a good a job as a I could have. Obviously this is a problem, because there are always things that you don't want to do that you have to anyway. Its made me wonder what I can do to get interested in the mandatory assignments in my life, as well as wonder what to do with my life when I graduate from college--because having a job I love and can actually enjoy and be good at is essential to me.
