Ralph Waldo Emerson advises to finish each day and forget any blunders, as tomorrow is a new day to begin serenely without past nonsense. Bobby Unser states that desire, not education or talents, is the one secret to a successful career. Pope John XXIII encourages focusing on hopes, dreams, and unfulfilled potential rather than fears, frustrations, or past failures. Johnny Carson recommends not continuing in an unenjoyable job, as happiness and inner peace from a liked job lead to unexpected success alongside health.

1. Ralph Waldo Emerson
Finish each day and be done with it. You have done
what you could; some blunders and absurdities
have 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.
Bobby Unser
Desire! That's the one secret of every man's career.
Not education. Not being born with hidden talents.
Desire.
Pope John XXIII
Consult not your fears but your hopes and your
dreams. Think not about your frustrations, but
about your unfulfilled potential. Concern yourself
not with what you tried and failed in, but with what
it is still possible for you to do.
Johnny Carson
Never continue in a job you don't enjoy. If you're
happy in what you're doing, you'll like yourself,
you'll have inner peace. And if you have that, along
with physical health, you will have had more
success than you could possibly have imagined.
