I think it's about how hard true love is to find. It doesn't matter how much money you have, when true love comes along, you've got to grab it, "before it's gone". "It takes so long" for love to show up. For some people it never shows up. Henley is talking to someone in his life here, or maybe its about himself. By "make love", he means open up and make that connection with her. Don't miss your chance.
