Never give up

I just settle down from my last holiday as well as my injured leg now my study mood is coming back to me after few weeks of schooling. Many assignments are thrown to my face by all the units of lecturers. I feel very sorry to myself that I do not start to do my revisions from the first topic of each units. Now I feel like catching up a train that never can be reach at all but what to do? I can just tell myself- NEVER GIVE UP!! I CAN DO IT......
