Decision making, after the fact
Critics are eager to pick apart complex decisions made by others.
Prime Ministers, CEOs, even football coaches are apparently serially incompetent. If they had only listened to folks who knew precisely what they should have done, they would have been far better off.
Of course, these critics have a great deal of trouble making less-complex decisions in their own lives. They carry the wrong credit cards, buy the wrong stocks, invest in the wrong piece of real estate.
Some of them even have trouble deciding what to eat for dinner.
Complex decision making is a skill—it can be learned, and some people are significantly better at it than others. It involves instinct, without a doubt, but also the ability to gather information that seems irrelevant, to ignore information that seems urgent, to patiently consider not just the short term but the long term implications.
The loudest critics have poor track records in every one of these areas.
Mostly, making good decisions involves beginning with a commitment to make a decision. That's the hard part. Choosing the best possible path is only possible after you've established that you've got the guts and the commitment to make a decision.
