Success can never happen without the journey (struggle).

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

There are no bad mistakes in maths, only discoveries.

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

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

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

Tomorrow is worth more than yesterday but less than today.

Procrastination makes easy things hard and hard things harder.

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

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

Don’t be afraid to work hard and find out how good you can really be.

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

We learn more from failure than we do from success.

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

Do what you have always done and you will always be what you have always been
