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 master has failed more times than the beginner has even tried

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

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Success is the sum of small repeated efforts, day in and day out.

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

It always seems impossible until it's done.

If you can understand just one thing thoroughly, then you will understand everything.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

The journey of a thousand miles begins with one step.

If you want to succeed, double your failure rate.

We all have two lives. The second begins when we realise we only have one.
