I am not very good at sitting still. I realized that when I was unemployed. Yet, setbacks are one of the great opportunities in life to recharge and reinvigorate your intentions.
I ran one mile this morning and one mile yesterday morning. It's going to be a slower comeback than I would like, but it's pain free.
The same can be said for mental stress as for physical stress. One must take it easy for the connections to repair. One must take it easy for the hormones to rebounds so that they can pump harder on the next go around. A very difficult aspect of long term goals happens to be long term setbacks. The larger the goal, the larger the dip. You get to become CEO by 25 or 35 years of awfully hard work. A Ph.D. takes years and likely months are spent seemingly chasing your tail with no apparent progress. Whatever it is you are doing, if it was easy, everyone would do it.
