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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Everything you want is on the other side of fear

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

Dreams don't work unless you do.

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

If you fail, next time fail better.

Life is full of opportunities. With every opportunity that is missed, another one is born.

The journey of a thousand miles begins with one step. 

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Don’t practice until you get it right, practice until you can’t get it wrong.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.
