Learn quickly and figure out things on the fly... for ten years. That's experience. :-) That kind of experience ends up giving you the confidence to attempt hard things that you would never have dreamed you were capable of. But - and this was the point of the OP for me - it always feels like you are faking it and have no idea what you are doing, every single time. In fact, if it didn't feel that way, then that would probably mean you stopped trying, stopped growing and doing new things and have actually stagnated in a rut.
