Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

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

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

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Run in the morning before your body figures out what you're doing

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

99% of genius comes from hard work, the remaining 1% comes from innate talent

Your attitude is everything. Pick a good one.

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

Hard work - a two way street where you get exactly what you put in.
