Success is not final, failure is not fatal.  It is the courage to continue that counts.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

I can is 100 times more important than IQ.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

It is never too late to turn an unproductive day into a productive one.

Pure mathematics is in its way, the poetry of logical ideas.

Success is not final and failure is not fatal. It is the courage to continue that counts.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Don’t hang your targets after you’re done shooting.

Success can never happen without the journey (struggle).

The road to success is like a staircase. If you want to succeed, double your failure rate

It is never too late to become what you might have been

A book a day keeps the stupidity away.
