We all have two lives. The second begins when we realise we only have one. 

There are no shortcuts to any place worth going.

The easiest person to deceive is yourself.

Knowledge is of no value unless you put it into practice.

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

There are no bad mistakes in maths, only discoveries.

Dreams don't work unless you do.

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

We learn more from failure than we do from success.

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. 

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

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

Shoot for the moon and even if you miss you’ll land among the stars/

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

You're not in competition with anyone but yourself. Outdo your past, not other people.
