One skill to rule them all

A keystone skill is a skill which can be used to enhance multiple areas of your life.

One of the most important keystone skills is that of conversation.

If you are really good at listening to another person, displaying curiosity and helpfulness, and communicating effectively…you will be a force to be reckoned with.

Since these are all skills, that means they can be practiced and improved. Doing so is well worth your time.
