Got a question for folks that I've been thinking about for the last few days: What's the best compliment you ever received from a co-worker (or, I suppose, your boss)? The one that has stuck with you and meant the most?
I'm an engineer and used to work in a very old-school production company (steel, fire, hard hats and fireproof jackets kind of place). The best compliment I ever got was from a grizzled 35-year-veteran of the company (did an apprenticeship with the company at 15 and never left, worked his way up to the logistics department from the shop floor). He told me all the "yellow helmets" (production workers -- engineers and supervisors have white helmets) liked working with me because I was very good at my job, but still "talk to us like you're one of us (i.e. not like the other engineers). And you listen to the answer when you ask a question." (Loose translation from the German.)
I've gotten other much more elaborate compliments on my work before, but that is the one that has really stuck with me -- that these cranky old dudes with DECADES more experience in the company both respected me and thought I was good as my job, but also genuinely knew and cared how much I respected them.
What's the one (positive) thing a co-worker has said to you that made the biggest impression?
