Knowledge is of no value unless you put it into practice.

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

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

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

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

It doesn’t matter where you start, it matters how you end

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

I think, therefore I am.

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

Skills are built not born.

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

It is never too late to become what you might have been

Don’t compare yourself to others. Compare yourself to the person you were yesterday.
