Be a Do-er Not a Critic
A non-doer is very often a critic-that is, someone who sits back and watches doers, and then waxes philosophically about how the doers are doing. It's easy to be a critic, but being a doer requires effort, risk, and change.
- Dr. Wayne Dyer

I have learned from 21st century to be a doer. I feel like there are many areas in teaching that I can (and have) risk a bit, change a bit and become a better teacher. As many others of you, I would like to say thanks for so much to think about and encouraging and helping me to be a doer.
