Change the way you look at things and the things you look at change.
Wayne W. Dyer
Everyone thinks of changing the world, but no one thinks of changing himself.
The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.
They always say time changes things, but you actually have to change them yourself.
The snake which cannot cast its skin has to die. As well the minds which are prevented from changing their opinions; they cease to be mind.
