Steve Siebold is the author of Mental Toughness, and gives pretty good advice on what it takes to be successful. In a recent email, he talked about focusing on the things we can control and not wasting time worrying about those things we can't. This particular message centered on getting fit and thus having the energy for opportunities when they arise. Too often, it seems, we worry about things outside our control and don't focus our energies on getting better in the areas we have under our control. It reminds me of the Serenity Prayer:
God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
