Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

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 practice until you get it right, practice until you can’t get it wrong.

I think, therefore I am.
