Subject: Re: Schumer's book tour postponed
Often, if you’re trying to accomplish something difficult, you have to attempt it and fail over and over again until you finally get it right.

I think that's true, but...when you "attempt it and fail over and over until you finally get it right" doesn't mean doing the exact same thing that got you to the failure. You have to tweak the attempts, otherwise you're doing the same thing over and over expecting to get a different result.
