Google them, go to the library, start reading that autobiography you’ve had sitting on the shelf, revisit a book or magazine article you love as a reminder of inspirational thoughts.

I just checked out the autobiography of Nelson Mandela, “Long Walk to Freedom” that I have wanted to read for a long time. Maybe I will start a revolution?
