I can is 100 times more important than IQ.

There are no bad mistakes in maths, only discoveries.

Tough times never last, but tough people do.

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

The journey of a thousand miles begins with one step. 

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

The journey of a thousand miles begins with one step.

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

Success is the sum of small repeated efforts, day in and day out.

Time is your friend, impulse is your enemy.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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.

The greatest enemy to human potential is your comfort zone

The temptation to quit will be the greatest when you are about to succeed

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.
