Dreams don't work unless you do.

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. 

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

Failure to prepare = preparing to fail

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

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

Tomorrow is worth more than yesterday but less than today.

We learn more from failure than we do from success.

We all have two lives. The second begins when we realise we only have one. 

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

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

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

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.
