You can have a big athlete that is in a "slump". But why is he in a slump? They say his confidence is low. But how is that possible if he's one of the best athletes in the world? You need to be able to have the strength to have a failure in your life and get over that failure. Have a relationship that didn't work, have a project that didn't work and be able to still bring the power and strength to overcome it.
