There are a lot of guys out there now who know they are not working as hard as other people. I can't fathom how they think.

I think in running, to be honest, that even though athletes are very dedicated and are willing to train and do whatever they need to do to prepare, more often than not they're not in a very professional environment where you've got a high performance director and a coach that are really monitoring your daily activities.

I can't tell you why a particular athlete would leave a certain coach, but I can tell you there could be many reasons. They could have personality conflicts. They could have misunderstandings. Lots of stuff can happen.

I didn't give myself enough breaks during the training year to recover. I didn't understand the power of periodization.

Whatever we accomplish in life, if it's solely for our own good, then it doesn't mean that much. The things you do that affect others in a positive way are the ones that count. Whatever facet of life you're in, God has given you a gift; do the best you can with that gift.

Early in my career I was accused of being overconfident and even cocky, but I really was confident that I had done the training and didn't see any other reason to say otherwise.
