Learn from Failure
There are two types of persistence. In the first type, we start having doubts and aren't sure about ourselves or about the plan we've set forth, but we press on anyway. We may not be certain about our ability, but there are some factors inherent in what we're doing that propel us forward.
The second type of persistence comes from something deep inside us. Persistence isn't just what we do; it's a part of who we are. If we're this type of person, it doesn't matter what the score is, what our record is, or what obstacles are in front of us; we're living a lifestyle that says, "We're not giving up."
