What is Love, to You?

With Valentine's Day coming up (eventually), what is love to you?

How can there be more love in the world?

(inb4 memes of "baby don't hurt me)

How should Valentine's Day be observed? (I think culturally there's a focus on romantic love, but here I have in mind a broader discussion of a care towards many random people with "random acts of kindness" and also inclusive of singles as there are less people getting married today)

I've viewed Valentine's day as having acquired a meaning of being a cultural celebration of "love" in general

(Religiously there may be interpretations of V-day as a recognition that "God is Love" and that "loving God" may be a kind of the highest expression of and experience of "love")
