I didn't hear it from someone in tech; in fact they are now doing house flipping. However, they embodied this 'success personality' quite explicitly. I can definitely relate to hosting parties with mixed moods. Over time you realize you have to host multiple kinds of events - this is more maintainable for having multiple kinds of friendships. I have friends who can be comfortable in any event I might have, but it is best to find those naturally rather than during awkward parties
