I have a funny quote for you:

There’s a difference between doing things right and doing the right thing.’ Doing the right thing is wisdom, and effectiveness. Doing things right is efficiency. The curious thing is the righter you do the wrong thing the wronger you become. If you’re doing the wrong thing and you make a mistake and correct it you become wronger. So it’s better to do the right thing wrong than the wrong thing right. Almost every major social problem that confronts us today is a consequence of trying to do the wrong things righter.”

It's not exactly matching your theme, because it's all about "doing". :)

I wonder who on earth is truly able to do nothing. Haven't met anyone. Even I am mostly doing something, if only it is thinking.
