We learn more from failure than we do from success.

Tough times never last, but tough people do.

Success can never happen without the journey (struggle).

Run in the morning before your body figures out what you're doing

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Mistakes have the power to turn you into something better than you were before.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

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.

Pure mathematics is in its way, the poetry of logical ideas.

Everything you want is on the other side of fear

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

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. 

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
