It is very tiring to make decisions. There appears to exist a popular perception that decision, once made, leads to some irreversible change to the currently “working state”. What, then, one has to decide is whether the change was good or bad, and so whether the decision made was right or wrong.
This judgement that follows after every decision invariably forces one to question whether it was worth the enforced change. The fear of making the wrong decision is the reason, more often than not, behind the lack inclination to change.
You can be deciding what gift to buy for someone or who to choose to be your life partner. It does not matter whether the decision to be made is critical or trivial. Our subconscious is always at work, judging our every decision.
However, it is up to you to not let this fear of judgement drive how you lead your life. It is easier to overcome the wrong decisions you make than to lead a life being too indecisive.
