As an athlete how many times have you wanted to quit, or just stop and give up? I know as a cross country runner there are times when it's just too hot, and I don't want to run, so I stop and walk, even though I know it will only put me at a disadvantage later. It's just so tempting when that person who's usually behind you passes you, or someone in front of you starts walking. It's times like these when we need something many of us lack: perseverance and endurance.
