I have failed so many more times then I have succeeded. It can be so easy to get caught up in the "failure" part but what I've found is that if you write out your goals and have a clear vision for what you know you want to accomplish, it gets a little easier to get on track after a setback. You assess what went wrong, what you could have done better, and you keep on moving forward. Remember, those who achieve greatly also take risks and do things that feel scary or intimidating to them.
"Success is not final, failure is not fatal. It is the courage to continue that counts." - Winston Churchill
