haaaaa...... i'm feeling the exact same thing right now....... i got my motivation by calling my friend who came me a lot of tension by talking really fast on how hard the exams were for the other school children....and she went on asking me whether i studied that or this or that....and so on and so on...... but it did work in getting me all tensed up and motivated to study for half an hour in a stretch..... so try calling someone like that....... tension always seem to work in making me study.... well all the best....i guess u will need it...:]
You are losing sight of the reward my friend. You need a clear sight on your goal and understand that greater achievements usually require greater sacrifices. Pump yourself up, and take a few minutes to remind yourself why you are improving yourself. It is all about habit. Once you "force yourself" a few times, it will get easier and easier. You will feel great about yourself and have more self worth. If you do not you will have guilt that only paralyzes. Now grow a pair and get in there!!! It's worth it!!!
