It is never too late to turn an unproductive day into a productive one.

I think, therefore I am.

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.

I can is 100 times more important than IQ.

The master has failed more times than the beginner has even tried

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

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

We all make mistakes. What matters is how we choose to move forwards from them.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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. 

Everything you want is on the other side of fear

The greatest enemy to human potential is your comfort zone

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.
