William Leffingwell

“Love isn't something natural. Rather it requires discipline, concentration, patience, faith, and the overcoming of narcissism. It isn't a feeling, it is a practice.”
― Fromm, Eric, The Art of Loving

“Is love an art? Then it requires knowledge and effort.”
― Erich Fromm

“The mature response to the problem of existence is love.”
― Erich Fromm, The Art of Loving

“Is love an art? Then it requires knowledge and effort. Love is not a spontaneous feeling, a thing that you fall into, but is something that requires thought, knowledge, care, giving, and respect. And it is something that is rare and difficult to find in capitalism, which commodifies human activity. ”
― Eric Fromm
