I created a poll that asked people what they desire most in a potential partner and a good personality seemed to be the most popular choice. Having a good, likable personality is important for compatibility.
Personality, as defined through text, is the combination of characteristics or qualities that form an individual's distinctive character. How can we judge someone's characteristics without judging our own first? How can we say we want someone humble yet we ourselves are chronic complainers? How can we say we want someone who's caring but we're too selfish to care about anyone else other than ourselves? So before we go looking for people who have nice personalities, have you checked yours yet?
These are the kind of things we often don't pay attention to because they're hard to see, but not impossible. We shouldn't have to wait for someone to point out these crooked places before we start fixing them straight.
