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. 

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

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

I have not failed, I've just found 10,000 ways that won't work.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

No one starts out on top. You have to work your way up.

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

There are no bad mistakes in maths, only discoveries.

Tough times never last, but tough people do.

Time is your friend, impulse is your enemy.

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

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

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.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.
