One of my favourite quotes by William James.
“Compared to what we ought to be, we are only half awake. We are making use of only a small part of our physical and mental resources. Stating the thing broadly, the human individual thus lives far within his limits. He possesses powers of various sorts which he habitually fails to use.”
How much could you truly create for this world if you consistently took yourself to your edge?
