Another pearl of his is to be "profuse in your praise". Even if it risks sounding empty or pure flattery, because it always leaves a good impression and works.
Profuse praise is so weird and off-putting to be a recipient of. I don't know what you're talking about. Maybe this was true however many years ago but it doesn't feel true all the time today.
For example, throwing in phrases like "with your experience, you would know that..." or "that thing you said was hilarious" make people feel good, hopefully while also being true. This is a huge part of likeability.
