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. 

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Everything you want is on the other side of fear

The bad news is time flies, the good new is that you're the pilot.

Dreams don't work unless you do.

Success is a journey, not a destination.

Fall down seven times, stand up eight.

Procrastination makes easy things hard and hard things harder.

Success is the sum of small repeated efforts, day in and day out.

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

The journey of a thousand miles begins with one step.

Procrastination is the thief of time and the enemy of success.

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

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

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