What is the best way to say "experience is the best teacher" or "experience teaches"?

Question

We're working on a translation of a school motto (solvitur vivendo) and looking for not just a good translation, but the way to say this with the most "punch". thanks

Answer 1

It sure is... but the school-fees are heavy, as Hegel would say. :/

Maybe: "The all of things is an infinite conjugation of the verb to do," by Thomas Carlyle, would have the "punch" you want?

Answer 2

To the cognition of the brain must be added the experience of the soul. - Arnold Bennett

or "Learn from Experience"

or (this one I just thought of)

Experience teaches what nothing else can.  

Answer 3

Live and learn
