Everything you want is on the other side of fear

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

Time is your friend, impulse is your enemy.

Failure is not the opposite of success, it is part of the success.

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

There are no bad mistakes in maths, only discoveries.

Tomorrow is worth more than yesterday but less than today.

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

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. 

If you can understand just one thing thoroughly, then you will understand everything.

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

Don’t hang your targets after you’re done shooting.

Success can never happen without the journey (struggle).

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