quotes on building self-personality by world leaders

“Finish each day and be done with it.
You have done what you could.
Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day. You shall begin it serenely and with too high a spirit to be encumbered with your old nonsense.”
― Ralph Waldo Emerson

“We are what we pretend to be,
so we must be careful about what we pretend to be.”
― Kurt Vonnegut, Mother Night
