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. 

If you fail, next time fail better.

There are no shortcuts to any place worth going.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

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

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

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

Don’t hang your targets after you’re done shooting.

Tomorrow is worth more than yesterday but less than today.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Procrastination makes easy things hard and hard things harder.

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