Sometimes wrong...

I have the role of "chief troubleshooter" in my engineering group. I have a bit of a nervous tic that forms when I hear absolutes like this.

Don't assume the customer is always an idiot. Don't assume ANYONE is always an idiot. It limits you as an engineer.

Listen to everything. You don't have any need to abide any of it, but listen to it all.

I've had some of the least-qualified people throw out something which absolutely ended up being insightful, although sometimes in a way they didn't expect.
