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. 

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Success can never happen without the journey (struggle).

A hero is no braver than an ordinary man, but he is braver five minutes longer.

In order to become better than anybody else you must first become better than yourself.

Your attitude is everything. Pick a good one.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Tough times never last, but tough people do.

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

Don’t hang your targets after you’re done shooting.

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

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