Write it down...numerous times... Have your friends tell you continuously you have to do the homework... Do the homework with your friends... When you think about it, do it immediatly... Reserve a time period to work... Do the things you like less first, then the things you like best... Promise yourself something (like a chocolate bar) you will have when you finish your work... I can give all those suggestions...but I still have the problem...dam**t anyway...try what I said... good grades are important for your future
