6. Repeat their mistakes
People make mistakes. It is in human nature to make some sort of mistake no matter how careful you are. What separates the masses from the mentally strong people is that the latter group will not repeat their mistakes. They sit down, find out what went wrong. They realize their initial mistakes and they learn from it. According to a study, it has been shown that the ability to learn from their personal mistakes and taking positives from it is characteristic that most leaders and entrepreneurs have.
