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

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

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. 

Everything you want is on the other side of fear

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

There are no bad mistakes in maths, only discoveries.

The journey of a thousand miles begins with one step.

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

Don’t be afraid to work hard and find out how good you can really be.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

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

Failure is NOT your destiny. Failure is the key to success.

Success can never happen without the journey (struggle).

Your attitude is everything. Pick a good one.
