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

Tomorrow is worth more than yesterday but less than today.

Don't fear failure, fear being in the same exact same place next year as you are now.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

Procrastination is the thief of time and the enemy of success.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Success can never happen without the journey (struggle).

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.

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. 

Try and do one thing each day that you would really rather not do.

The greatest mistake we make is living in constant fear that we will make one.

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

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