Procrastination is number one on my stupid list. You still end up exactly where you didn't want to be, doing exactly what you didn't want to do, with the only difference being that you lost all that time in between when you could have been doing something fun. Even worse, you probably stayed in a stressed-out, crappy mood the whole time you were avoiding it. If you know something is inevitable, do it and get it over with. Move on. Life is short.
