As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives
Henry David Thoreau
So please ask yourself: What would I do if I weren’t afraid? And then go do it.
