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

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

Time is your friend, impulse is your enemy.

Our fixed mindset builds our cage, fear keeps us in it.

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.

Success is the sum of small repeated efforts, day in and day out.

The greatest enemy to human potential is your comfort zone

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

You cannot escape the responsibility of tomorrow by evading it today

Tomorrow is worth more than yesterday but less than today.

Shoot for the moon and even if you miss you’ll land among the stars/

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. 

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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