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. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

Procrastination makes easy things hard and hard things harder.

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

A book a day keeps the stupidity away.

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

Your limitation - its only your imagination.

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

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

Hard work beats talent when talent doesn't work hard.

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

Time is your friend, impulse is your enemy.

It is never too late to become what you might have been

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.
