For me, it has been this Eleanor Roosevelt quote:"Great minds discuss ideas; average minds discuss events; small minds discuss people."The quote above has helped me classify hundreds of conversations I've had with different people over the years and has generally helped me make better choices with respect to the kind of conversation I'd like to have.It also acts as a people filter of sorts, and I have used that quite extensively to filter out people who spend way too much time talking about 'people stuff' over discussing events or ideas (in any field).What's your go to quote?
