The Only Sure Way To Avoid Making Mistakes Is To

Anyone who has never made a mistake has never tried anything new.

The only true wisdom is in knowing you know nothing.

If you want to improve, be content to be thought foolish and stupid.

If at first the idea is not absurd, then there is no hope for it.

To be wronged is nothing, unless you continue to remember it.

Failing isn't bad when you learn what not to do.
