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. 

Dreams don't work unless you do.

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

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

Tomorrow is worth more than yesterday but less than today.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

Fall down seven times, stand up eight.

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Don't fear failure, fear being in the same exact same place next year as you are now.

Your attitude is everything. Pick a good one.

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