"The health of a engineering environment is directly proportional to the number of times you hear the words 'I don't know.' "
Reasoning: If you never hear those words, as I haven't, then it means people are BSing up the wazoo. No one knows everything.
I've lived by the belief that to really know something at work you have to ask about a thousand stupid questions. The less stupid questions you ask the less you know.
It's better to ask the stupid questions up front when you first start and the embarassement level at not knowing is lower than to wait 8 months...
The most frustrating thing I've experienced far too often is being in meetings or conversing with people that never ask those questions. And in response to your questions they have this ability to befuddle and amaze you with verbage. At the end of the conversation you still don't understand what the awnser to your question was and is.
At a certain point you realise they don't have a clue what they are talking about. People who really know everything they are supposed to know will freely admit what they do and do not know.
