You're presented 2 boxes: Box A and Box B.
One of the boxes has a million dollars in it. The other contains a box of Smores Pop Tarts.
You're truthfully told that Box A has a 55% chance of having the money. You have to choose one.
What do you do?
You pick box A. You open it up. GARRR! It's the pop tarts!
Did you make a bad decision? Most people would say so. In fact they might live their entire lives regretting it, and wishing that they had chosen Box B instead.
But the quality of your decision is outcome independent. Hindsight is 20/20.
In fact, in retrospect based on the intelligence you had, you made the best decision. The perfect decision.
Dont' worry. Keep making good decisions, and good outcomes are bound to follow.
So eat the pop tarts. Enjoy them. And pat yourself on the back for a job well done.
