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. 

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Mistakes have the power to turn you into something better than you were before.

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

Go as far as you can see, when you get there, you’ll be able to see further

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Success can never happen without the journey (struggle).

No one starts out on top. You have to work your way up.

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

Your attitude is everything. Pick a good one.

Patience is when you’re supposed to get mad, but you choose to understand

Lose an hour in the morning and you will spend all day looking for it.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

He who has begun his task is half-way done. Have the courage to begin!
