It reads 6 ways to making others like you.
I think though the author says 6 ways, the core value is knowing LIBIDO, from which you will gain lots of benefits, if you use it appropriately.
Libido is a psychological proper noun, which means the desire and pleasant for everything. John Dewey puts it into "the desire making people feeling they're important".
So you have patience to listen, you praise others sincerely, and you talk topics about others are interested in, this will naturally makes you be welcomed to others.
