You cannot show that you have any doubt in what you are doing today: even if you do! Having conviction in every decision you make is vital right now, because too many people are looking to you for the confidence that they themselves are lacking. To show doubt is to start a domino effect that would only create bad news. Changing your mind over and over again is a bad idea: and it could really negatively affect your reputation. Stick to your plan and don't waver.
