If you want to make the world a better place, take a look at yourself, and make a change.

As a man changes his own nature, so does the attitude of the world change towards him.

If you want to change the world, start with yourself.

Our greatest ability as humans is not to change the world; but to change ourselves.

True change is within; leave the outside as it is.

We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction.
