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

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

Failure is not the opposite of success, it is part of the success.

I think, therefore I am.

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

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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.

Try and do one thing each day that you would really rather not do.

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

Success can never happen without the journey (struggle).
