Good thing about being founder is that you don’t have to remember where you have been wrong. Because people will come and tell you. Some will tell you subtly by showing data and some will tell you directly out of frustration and anger. Both are good for you. It forces you to make sound decisions next time.
However, it may impact negatively in your decision making process. Next time, your mind will be adjusting your decision to include other person’s reasoning. Avoid that. Use feedback as input data to your decision, not to make them happy. Make hard choices whenever you have to.
