Your question is badly worded. A person IN LOVE with themselves is a narcissist. But everyone should love themselves. The difference is the level of attention one gives to oneself. Someone who loves themselves is a balanced person. A person in love with themselves is egotistical and cares for themselves above others.
Lover: 1. showing unconditional love for all things, even in the face of hate, for the recognition that all, even hate, is born of love; hence we are all love, and a lover embraces all love. 2. A being that lives to connect with the love inherent to all life. 3. A being that lives to love, not hate, and even embraces hate as love. 4.
