You can have results or excuses, not both

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

The master has failed more times than the beginner has even tried

99% of genius comes from hard work, the remaining 1% comes from innate talent

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Never underestimate the importance of small steps. small steps = big changes. 

I think, therefore I am.

If you want to succeed, double your failure rate.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

We learn more from failure than we do from success.

Success is the sum of small repeated efforts, day in and day out.

Time is your friend, impulse is your enemy.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Hard work beats talent when talent doesn't work hard.
