If the best is possible, than good is never enough and only do the best.

It's not enough that we do our best; sometimes we have to do what's required

In art the best is good enough.

Better is the enemy of best.

We all want to trust someone ,but we all think that what we see is real and the truth but if we truly did have vision, we would see the truth in most people and be more vigilant and careful with ourselves.Gary F Evans..

If something is not good enough, stop doing it.
