Tynan — that’s his first name, and he likes to go by just it — has written books about world travel, living in an RV and picking up girls. But the overarching theme of his blog is the good habits he tries to follow, and hopes other people will follow, too. He thinks we should have more friends and fewer acquaintances, for instance, and should worry more about being on time. That may sound boring and/or annoying, but it’s not: He gives his advice in a colorful, engaging manner. And if you fail to live your life like Tynan, it’s O.K. — he’ll never know.
