Others can stop you temporarily, only you can do it permanently.
Your work is to discover your work and then with all your heart to give yourself to it - Buddha
Leaders should lead as far as they can do then vanish. Their ashes should not choke the fire they lit. - H.G. Wells
Knowings others is intelligence; knowing yourself is true wisdom. Mastering others is strength; mastering yourself is true power.
