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

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

Pure mathematics is in its way, the poetry of logical ideas.

Procrastination is the thief of time and the enemy of success.

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

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

Everything you want is on the other side of fear

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.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

Tough times never last, but tough people do.

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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