Love is an expression and assertion of self-esteem, a response to one's own values in the person of another. One gains a profoundly personal, selfish joy from the mere existence of the person one loves. It is one's own personal, selfish happiness that one seeks, earns, and derives from love.
Ayn RandI shall choose friends among men, but neither slaves nor masters. And I shall choose only such as please me, and them I shall love and respect, but neither command nor obey. And we shall join our hands when we wish, or walk alone when we so desire.
Ayn Rand
