It's good to strive for better, but perfect will allude you.
We make a mistake when we obsess about perfect because perfect doesn't happen.
I like this quote attributed to Voltaire,
"Perfect is the enemy of good."
So as we move forward with individuals, ideas, and initiatives, we need to strive for the good, and not "let perfect get in the way of good." (quote attributed to former U.S. Senator Edward Kennedy).
