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. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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.

The journey of a thousand miles begins with one step. 

Everything you want is on the other side of fear

Dreams don't work unless you do.

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

The wise person knows that no answer is also an answer

Try and do one thing each day that you would really rather not do.

Your attitude is everything. Pick a good one.

Tough times never last, but tough people do.

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

There are no bad mistakes in maths, only discoveries.
