Fostering others mental well-being/self-esteem 3

I would say that in large part, (and referencing adults) one is responsible for one's own self-esteem, and short of illness one's own mental well being as well. Personally, I find the need that some people have to be handing out back pats and verbal blow jobs constantly, in apparent expectation of receiving the same in return, rather childish and repulsive.

Give praise when it is deserved, not just for showing up and continuing to exist. To do otherwise diminishes praise given for real accomplishments.
