Hitting The Wall

OK... So for the past few days I've been hitting the wall, and I can't seem to break through. Often times I sit and think about what is exactly the meaning of my mental blockage, but to no success. Not knowing is what drives me crazier. However, somewhere deep down inside my heart, the echos of each heart beat sing me a tune, and they tell me that I need to slow down... and not try to move ahead of time. There are many things that I would like to accomplish NOW! but each of those "things" require time... I'm impatient I guess... But how do you erase the assumptions and images of the future? How do you focus only on the present?
