We can change the world around us in different ways. You do not have to paint on the walls, but you can influence how our world looks and what is in its surroundings.
We can influence what the world around us is preparing for us in our city. By influencing these individuals, we can ensure that the colors of our streets are appropriate.
When we persist in our endeavors, then the changes will be as we want.
We can not, of course, give up and despite some setbacks forgive. We must strive for the end.
