Those who act as if they know more than their boss seldom do.
Being right half the time beats being half-right all the time.
The best vision is insight.
Thinking well to be wise: planning well, wiser: doing well wisest and best of all.
When one seeks assurance, there's none from those who respond, Now, don't you worry about a thing. If you weren't worried, you wouldn't have asked. If you are concerned, it's nice to know that those you query are, too. I'll take a worrier any day over a platitudinous reassurer.
Noone's a leader if there are no followers.
