Work hard, Play hard

I've been trying to live my life with the above phrase as a guide, but I'm having trouble with it. The thing is, I can't seem to go all out either way. I can't work hard, nor can I play hard. It's all half half, which annoys me to no end.

It's so frustrating. When I try to study, I keep thinking about something else that I want to do. And when I'm out, or playing around, I'm feeling guilty about fooling around instead of studying. Dumb isn't it.

I believe we should live life to the fullest. But the problem is that I can't seem to live my life the way I believe I should be.
