There is a theory glazed over in every freshman economics course on the way to supply side economics and demand side – I’ve already lost you. Economics might not be your cup of tea, but the theory is worth a listen. It goes a little something like this: Should Tiger Woods mow his own lawn? That’s it. The answer is an easy one. No. He has people for that. He should be golfing. The term for that is called opportunity cost. Why is there even a theory about that? Time management is why.
