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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Knowledge is of no value unless you put it into practice.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

The temptation to quit will be the greatest when you are about to succeed

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Failure is NOT your destiny. Failure is the key to success.

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

99% of failures come from people who have the habit of making excuses.

We all have two lives. The second begins when we realise we only have one. 

The bad news is time flies, the good new is that you're the pilot.

You can be shown the path, but only you can make the first step.

Just stick with it, what seems hard now will one day be your warm up.

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

The wise person knows that no answer is also an answer
