A teacher is never too smart to learn from his pupils. But while runners differ basic principles never change. So it's a matter of fitting your current practices to fit the event and the individual. See what's good for you might not be worth a darn for the next guy.

I never wore a tie voluntarily even though I was forced to wear one for photos when I was young and for official events at school. I used to wrap my tie in a newspaper and whenever the teacher checked I would quickly put it on again. I'm not used to it. Most Bolivians don't wear ties.

You never know what's going to happen. My mother was an English teacher. If someone had told her that I was going to write a book she would never have believed that. So you can never say never.

I was a mimic when I was a child. I mimicked the teacher and made friends that way actually. That was a very subversive activity because I was a goody-goody who never got in trouble. But if I went off in the corner and mimicked the teacher people loved it.

I never had to learn English French and German because I was brought up as all three languages. I had a private French teacher before I even went to school. That helped a lot.

A teacher affects eternity he can never tell where his influence stops.

We can teach a lot of things but if the teacher can't relate by talking to a group of friendly students he'll never be a competent teacher.

A teacher is a person who never says anything once.

I didn't feel any remorse or sympathy if I injured a rival. I went over the top a few times but I never broke anyone's leg.

I never ask for mercy and seek no one's sympathy.
