Lessons learned are quickly forgotten unless they were learned in terror, or sorrow, or shame. Wisdom can always be rented for free, but it must be purchased with pain.

Without courage to be afraid, sad, subject to ridicule, there is no learning.

Courage must start with yourself. Having the courage to tell yourself what you are afraid of, telling yourself something that challenges doesn’t fit the idea of who you are. It is going to be painful, do it anyway.
