This is not a rule, it is human nature. Just think about it for alittle bit. Most of the time you are right about your decision, but you change it. Then it bites you in the ass.
Don’t let your indecision and immature way of thinking get in the way of your first logical reaction or reasoning to the problem, task, or dilemma at hand. Remember that when it is all said and done you are the one experiencing the outcome of your “choice”.
As you go through life remember the good and the bad decisions you made, determine which ones were right on with your first instinct and constantly learn and keep on improving, because that is one of the ways you truly grow up.
