We don't always know what we need to get fired up until it happens; it's often different for each person. There are plenty of famous people who do credit rejection as giving them the kick they needed; Michael Jordan does very clearly, for example. Or, "Can't sing. Can't act. Can dance a little.". That one worked out okay too.
