When you have a certain level of confidence in yourself, you are sure you cannot make a wrong decision and everything you do is pre planned. All for certain reasons. Legitimately being honest and truthful with yourself. No delusions.
As long as you are not hurting other people, which could be debated what that really means, be fully confident and precise in actions. Then live with them!
The process of deciding takes too long and once the doubt creeps in, that is when the confidence becomes non existent. You wind up in the mosh pit of life. Some may like that which is fine because you do not need to think.
But most become anxious because they have no control. Your life literally becomes a remote controller. In your hands and I know when you lose that remote, a feeling comes over you of panic, loss and confusion. The search is on!
