A friend of mine was given this in the 60s when  he first came to AA and I'll pass it on to you here.

I'd rather see a sermon      than hear one any day;
I'd rather one should walk with me      than merely
tell the way. The eye's a better pupil      and more
willing than the ear, Fine counsel is confusing,    
but example's always clear; And the best of all
preachers      are the men who live their creeds, For
to see good put in action      is what everybody
needs.  I soon can learn to do it      if you'll let
me see it done; I can watch your hands in action,    
but your tongue too fast may run. And the lecture you
deliver      may be very wise and true, But I'd rather
get my lessons      by observing what you do; For I
might misunderstand you      and the high advice you
give, But there's no misunderstanding      how you act
and how you live

Hope this helps
