Listen to the Mustn'ts by Shel Silverstein

I ran across this poem today by Shel Sliverstein, and it made me smile. It's so important that people, young people especially, know that they should not hold themselves back in their goals to make themselves the best people they can be.
The world is so full of opportunity if we believe in ourselves and our abilities to succeed in doing good and great things!
