Start a movement
Stand up for something. If you are always waiting for a change to happen, you may be waiting the rest of your life.
If you want to be a writer, write. If you want a cleaner city, start cleaning. If you wish people cussed less, start a no cussing club. Pretty soon, people just might start following you.
Start with the man or woman in the mirror. You may not be the most popular or get the most publicity, but by standing up for something and being the change you want to see in the world, you will make a difference.
It starts with you. It starts today.
