I personally think love is accepting someone (even yourself) fully and unconditionally for who they are in every way and supporting them always. It's not "hey i think you look good" or "I'm a good person," it's shit like setting aside something important for you and replacing it with something more important for the both of you for now. It's showing that you care in ways that actually make everyone involved feel loved. Sometimes it's jjst shutting up and listening. But no, it's not all self love/motivation, love is almost entirely giving yourself and life to someone you care about and trust. That's what love is.
