A businessman needs a laptop. Athletes need massages and the right diet.

There's always a point where you get knocked down. But I draw on what I've learned on the track: If you work hard, things will work out.

Running was like the friend that never left. It was just always there.

Stepping on that line for me, it will be about facing my fears.

I never have prayed to win a gold medal at Olympics and never will. The Lord is my Shepard and I shall not want. May His will be done.

Success is always an easier motivator, because you want more of it. But I've also been motivated by failure. Had I medaled in London, I don't think I would be one of the few that have gone to a Summer and Winter. I would have been content with that medal. Instead, I used that failure to go to the Winter Olympics. I always tell people that failure can be one of your biggest motivators if you just have an attitude adjustment about it.

Believe it or not, Twitter calms me down. I enjoy interacting with people.
