Ok, first off great question. I sometimes find my self having the same problem. I do a few things to motivate me. First i think how much i absolutely love this game, and what i would be like with out it. Then i push my self to to my limits to make sure i dont lose the opportunity to play this game. Secondly, i picture every play is do or die, if you dont score/get a stop i loose. This also pushs me a little more. If you truly love the game and think of these to things intensity will never be a problem. WARNING though, make sure you dont go to hard/fast. This can have a negative affect on your game. Keep ur mind slow and your game fast and your game will go to the next level. I hope this helps and good luck. Dont stop improving!
