There is no elevator to success, you have to take the stairs.

Never underestimate the importance of small steps. small steps = big changes. 

I think, therefore I am.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

The greatest enemy to human potential is your comfort zone

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Procrastination makes easy things hard and hard things harder.

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 easiest person to deceive is yourself.

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

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

There are no bad mistakes in maths, only discoveries.

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