Love isn't luck, it's an art you learn
Most people treat love as a matter of luck: you fall in love, you meet the right person, or you don't, and then it's just bad luck. Fromm opens the book by attacking that idea head-on. To him, loving is an art, in the same sense that playing guitar is an art: it takes theory and practice, not just desire.
This changes the question we usually ask. Instead of asking why the right person hasn't shown up yet, the question becomes: have I really learned how to love, or have I only learned how to want to be loved? Most of people's effort goes into becoming attractive and getting chosen, and almost none into developing their own capacity to love.
The author compares the pursuit of love to the pursuit of any other complex skill: nobody expects to play piano well without studying theory and practicing every day. Yet with love, people expect that feeling the right thing is enough, as if the feeling alone could sustain a relationship over the years.
