Surprisingly enough, the outcome of most of those situations turn out quite nicely. Better than expected. Your self-doubt only make matters worse and ultimately can hurt your chances of doing something great. Therefore, like the quote says, you have a lot more to offer than you give yourself credit for. You shouldn't second guess yourself, nor should you think even remotely for a second you cannot do something. That single second gives you the time to fear, and we all know "the only thing we have to fear, is fear itself."
