It is called accountability, when you are the boss, no matter what happens the blame starts and ends with you. You can do everything right, your staff can be perfect in execution, and guess what, it doesn’t work out.
You can give up “flight” on whatever you dream or goal was, and give yourself an excuse like “it was too hard,” “I was making no progress,” and so on. While you can justify your reasoning for giving up and it can all be valid. But at the end of the day, you will never achieve what you set out to achieve. But from some this is a security blanket. You would rather talk about how you “could have been” great at something instead of risking it all, or putting yourself completely out there and, well actually becoming great.
