Self Improvement Made Easy

I seriously want to work hard, but I always find myself thinking "Oh, I got two days" or "its not due for a week, so i’ll start it in a couple days" but i can never get myself to it. I believ it is a serious problem because I can’t quite get myself to keep my mind on one thing. I always wander off and can’t focus. What do you recommend? Do you know any individuals who deal with this on a daily basis? And, finally, how do they cope with it?
