High self esteem means we see ourselves as good and capable, that we're "secure" in our value or worthiness. Low self esteem means we see ourselves as not quite good enough, not measuring up. Every parent wants their children to love themselves, to be confident, happy people. There is no such thing as self esteem being too high. We cannot see ourselves as too good, too capable, too worthwhile, and that actually allows us to become more generous and caring people.
