If you do things right people won't be sure you've done anything at all.
Some one I have worked with for over a year just noticed that I put extra leather pieces on my left light work gloves. He thougth I had found some company that sold gloves with more leather on one glove than the other of a pair. And it's not like he had no reason to suspect, I have patches on my work pants and work boots.
Other stuff on that quote:
It's the last line in the futurama episode that I got my brother hooked on the show with. When God explains how to be God.
It's the same idea as something chip foose said on an early episode of rides (or overhauling) as his philosophy on altering cars. and one step below "beauty in simplicity" its mine too.
