If you were to pick one thing to do, one habit to form, what would it be? You would certainly have to consider your ambitions. What are you trying to accomplish? What are your goals? Then putting all that together, what is the one thing that if you did that everyday would have the greatest impact on your life?
Outside of anything else, accomplishing nothing, what is the one thing that if you did everyday, you would at least accomplish something and that would be enough to propel you forward even on the bad days?
The one thing is definitely something worth contemplating.
