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 temptation to quit will be the greatest when you are about to succeed

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

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

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.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

Mistakes have the power to turn you into something better than you were before.

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

Hope might be a good breakfast, but it makes a very poor dinner

Success is a journey, not a destination.

FAIL - First Attempt In Learning

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

You can hire a tutor but you can't hire someone to practice for you.

The easiest person to deceive is yourself.
