Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

The journey of a thousand miles begins with one step. 

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

Tomorrow is worth more than yesterday but less than today.

There are no shortcuts to any place worth going.

You're not in competition with anyone but yourself. Outdo your past, not other people.

You can hire a tutor but you can't hire someone to practice for you.

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

Hope might be a good breakfast, but it makes a very poor dinner

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

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

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.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Tough times never last, but tough people do.
