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 journey of a thousand miles begins with one step. 

We all make mistakes. What matters is how we choose to move forwards from them.

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

MATHS = Mistakes Allow Thinking To Happen

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

99% of failures come from people who have the habit of making excuses.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

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

Success can never happen without the journey (struggle).

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

We learn more from failure than we do from success.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.
