Setbacks are personal reminders of how much you have to want it, whatever “it” may be. They urge you not to get too comfortable with life. To never be complacent with what you have, but instead, to work hard for what you know you deserve. Humility is never to be mistaken for insecurity or self-doubt. It is self-growth. A chance to get in touch with the part of you that says, “I can’t.” A chance to respond by saying, “Yes, you can. You just have to learn. You have to knock down the walls, and be open to learning.” 

Delay. Turn for the worst. Side-trip. Fuck up. Failure.

To me, they’re all synonymous with “experience.” And without experience, you’ll never get anywhere.
