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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

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

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.

Time is your friend, impulse is your enemy.

No one starts out on top. You have to work your way up.

Procrastination makes easy things hard and hard things harder.

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

The journey of a thousand miles begins with one step.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
