our culture of optimizaiton tells us to make things better and better.
Fear of mistakes leads to the search for the best possible way to do things.
Rationally, looking for the best is a huge hinderance in realistic doing. It is like weights on one's hands when doing or planning.
The rule is simple. A good deal should be taken.
The main question is whether one acts out of the willingness to get his wants, or out of fear of making a mistake or losing some bette (imagined) option.
Acting out of fear, is irrational and suboptimal, too.
The enemy of the good is the best. Hesitation for fear of maybe there is a better way, is a losing strategy in my mind and experience.
