"Teaching
is the best way to learn, I'm still convinced of that; by passing
on our knowledge we continue to discover and learn. Moreover, this
activity forces us each time to a new formulation of what we want to
express, forces us to new [attempts], [a] constant search of new methods.
The constant links with youth helps us to always have a youthful
outlook, make us able to surprise ourselves constantly.."
