Compliment people more. Many people have trouble thinking of themselves as smart, or pretty, or kind, unless told by someone else. You can help them out.
I know that almost nobody hears too many sincere compliments. Compliment them to their face. Then, compliment them behind their back. Practice naming pleasant feelings you have about people, as soon as they bubble up, in the moment: “It’s always fun to see you.” Lower the resistance around this to zero.
