Slow Progress

Do not be discouraged with your slow progress; for slow progress is better than no progress at all. 

If you compare where you were to where you are, you will realize how far you've come. If you compare where you are to where you will be; you will realize that though you've reached far, you still have a way to go. 

When discouraged by the slowness of your progress just remember that a small step forward is better than no step at all and far better than a step backwards.

Every inch forward will eventually build up the momentum necessary to reach the speed that you desire.
