Failure to prepare = preparing to fail

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

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

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

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

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

Just stick with it, what seems hard now will one day be your warm up.

Time is your friend, impulse is your enemy.

The greatest enemy to human potential is your comfort zone

You cannot escape the responsibility of tomorrow by evading it today

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

There are no shortcuts to any place worth going.

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