You're not wrong - I have to watch myself to be sure I don't fall into that trap. I hope I succeed in bringing forward valuable lessons, but none of us are perfect. In addition, the advice I find myself giving most often to a variety of people is to stop saying, "This is what we did back when I worked at X". If you cannot abstract it into broader reasons why an action is applicable and helpful to the current situation, then having done it before is simply an anecdote.
