Do what you can, with what you have, where you are. The person doing the most talking is doing the most learning. In creating, the only hard thing is to begin. It's what you learn, after you know it all, that counts. Education must not simply teach work it must teach life.
Experience is the best teacher.
It gives the test before presenting the lesson. Be a guide on the side, not a sage on the stage. Jump at the sun, you may not land on the sun, but at least you you'll be off the ground. Perhaps there's not life after death . . . Blessed are the flexible, for they shall not get bent out of shape.
