Change is inevitable, constant, and necessary.
And when you think about being an agent of change, there is one simple thing that is worth remembering: start with yourself.
Changing yourself is possible, it is under your control, and chances are that by changing yourself you are also going to change the people and the world around you.
Yesterday I was clever, so I wanted to change the world. Today I am wise, so I am changing myself.
Rumi
