Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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. 

We all make mistakes. What matters is how we choose to move forwards from them.

Fall down seven times, stand up eight.

There are no shortcuts to any place worth going.

The greatest enemy to human potential is your comfort zone

The temptation to quit will be the greatest when you are about to succeed

Failure to prepare = preparing to fail

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Hard work beats talent when talent doesn't work hard.

I think, therefore I am.

Never underestimate the importance of small steps. small steps = big changes. 

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

It is never too late to turn an unproductive day into a productive one.

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.
