You can talk all you want about having a clear purpose and strategy for your life, but ultimately this means nothing if you are not investing the resources you have in a way that is consistent with your strategy.

My brother was a big marathoner. He was a great collegiate runner at Beloit College. He won his conference's races, and he did tons of marathons. I would go out and run with him every once in a while just to hang out with him.
