We all love challenges.
As you step every day and we're going to see challenges, we going to see failures, we should certainly learn from the failures and be gracious with our successes too as well.
Any athlete or any actor who's preparing for a long time to step on a stage or step on a field or step on a movie set, who suffers an injury right before you're getting ready to perform or to execute - it is a massive challenge that's thrown your way that you didn't expect.
