The person in love finds only a dream, a notion, an ideal. You fall in love with nothing but your own dreams - the only carriers of your true longings. Sometimes you manage to personify your dreams in another. Sometimes it’s not a single-player game. This doesn’t make love any less primal or selfish.
Some people would tell you that it's impossible for you to become successful in your line of passion. But don't be distracted by them because it is only you that need to believe in your dream in order for it to manifest. The vindication of your success doesn't need the whole world or anybody to cosign your passion for you.
