A CAN or a WILL?

I have a poster in my classroom that originally had “YOU CAN CHANGE THE WORLD.” Years ago I carefully crossed out the word “CAN” with whiteout and replaced it with “WILL”. I hope students understand the power they have to change the world, for good or bad. I hope that I have some small influence on this world. How sad it would be to live your life and come to the end of it realizing you have not made someone smile, or helped your kids find their way in life. I want to be a ‘WILL” person, not a “CAN” person. What about you?
