To review your steps can be self-discovering, you will take into account your weaknesses and strengths and you will know how to handle a similar issue the next time. On the other hand, keep in mind that you learn when you fail, not when you succeed.
It is a cliché phrase, but it is the absolute truth. Remember and think that success left you a great personal learning. However, when you make a mistake, you learn how you should not act again and this in itself represents a success.
