It is a tragedy when you do not choose the life you want to live. Some people don't have a choice because of where they were born.
You are likely not one of those people if you are reading this as you have access to the internet, are probably educated, and have more choices than you could ever imagine.
Don't worry about failure or looking foolish doing the thing you know you were put on this earth to do. Instead, worry about regretting your choices in life and never living the way you were meant to live.
