Don't cling to that rule-based prescriptive grammar all the time. Delight in the creative aspects of self-expression. Believe in change. If words can do it, so can we. Learn to use livelier language to inspire everyone else around you.

Be the fire in your school. Don't let your spirits get dampened by stupidity. Just get on with it. The best energy comes from renewable energy sources. Renew yourself, and you'll have more energy to help renew others.
