Funny how your legs feel like lead weights when you simply don't want to face a tough job--but when you coach yourself forward to do that job with good energy, good purpose, and a vision of the good results of such work your legs lighten up and you're on your way.
The more we procrastinate on the tough jobs in life the bigger weights we create, weights that obstruct our good living. So in the face of meaningful, purposeful tough jobs, the best advice is JUST DO IT!
