There are no shortcuts to any place worth going.

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 mistake we make is living in constant fear that we will make one.

You can hire a tutor but you can't hire someone to practice for you.

You cannot escape the responsibility of tomorrow by evading it today

Skills are built not born.

The journey of a thousand miles begins with one step.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

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

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

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

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