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

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

The bad news is time flies, the good new is that you're the pilot.

Time is your friend, impulse is your enemy.

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

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

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. 

The greatest enemy to human potential is your comfort zone

The journey of a thousand miles begins with one step. 

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

Your attitude is everything. Pick a good one.

He who has begun his task is half-way done. Have the courage to begin!

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
