I claim myself guilty at being a hard worker when it comes to school assignments, projects, and if I had one at the moment, work. I can't help it, but I've always been the over achiever amongst people. I never settle for doing what's the minimum requirement of something, but rather I go beyond what's needed. I consider it a gifted habit and a curse. While working extremely hard pays off in the long run, it can sometimes keep me back from doing the things people my age would normally rather be out doing. I will say that I do have my moments of procrastinating, however.
When it comes to other things, such as chores or even self interests (like here for instance), there are times when I just don't feel up to pushing myself and working hard at it, but I end up slacking off a bit. I usually pick myself up after awhile though, but I guess you could say that when it comes to things that's not so high in priority, I might not always take it as seriously as other things.
