Take time you remember your life. You own your history. Switch your perspective and go through your life with different perspectives. What ever made you feel like a failure at the time, switch and look at it from the complete different angle. Everything you have done have helped you develop. Every experience is part of what you are. Einstein said what you are is the result of everything you have chosen to do and not do. Live life and love life and enjoy it, its yours for the making.
