Where there any opportunities in the your life that you felt like you blew?

That one interview that could have changed your life and career. That kiss you should have delivered on the cheek of the girl or guy you liked at that date and time. Stooding up for a friend when they needed you the most. Or didn’t raise your hand in third grade with the right answer because you were to scared.-I know the opportunites that I have missed, I would like to read from other personal experiences.(By the way I’m new to this, Fluther)
