It's not whether you get knocked down.
……It's whether you get up again.
An optimist sees an opportunity in every calamity;
a pessimist sees a calamity in every opportunity.
Ralph Waldo Emerson
Nothing great was ever achieved without enthusiasm.
The will to do springs from the knowledge that we can do.
Few things are impossible to diligence and skill.
Lost time is never found again.
No problem can stand the assault of sustained thinking.
Victory belongs to the most persevering.
Leave no stone unturned.
Norman Vincent Peale
Plan your work for today and every day;
then work your plan.
Failure is only the opportunity to more intelligently begin again.
I start where the last man left off.
What the mind of man can conceive and believe,
the mind of a man can achieve.
