However, if you are not confident with your decision making skills, what you can do is to act against your initial decision. However, this only works if you don’t know you are going to reverse your decision because knowing you are going to reverse the decision may affect your initial decision. The best thing you can do is to toss a coin after a decision is made and based on the coin tossing result reverse the initial decision. Now, if you understand that coin tossing result is random, you may eliminate the process of making the initial decision.
Hope this helps.
