"Life is something like a trumpet. If you don't put anything into it, you don't get anything out."
-W.C. Handy 1873-1958
I add this quote to a huge picture (usually hand drawn) of a trumpet. The parts of the trumpet are labelled, but you could do the bulletin board without labelling the parts. It would be more just for decoration then, but hey! we all need to spice up our rooms sometime!
