Hey there, smarty pants! You Number 5s might wear that nickname well because you're pretty clever—sometimes too clever for your own good. You have an incredible thirst for knowledge, but you don't glean all your information from books. As your Observer moniker suggests, you divine information from watching others—but not always from an up close and personal perspective. That doesn't mean you're not good one-on-one, however. In fact, you'd probably prefer an intimate setting with intelligent conversations over a rockin' party with a crossfire of smack talk. You've got a brain like a sponge and the work ethic to wring it dry. Whether it's finding a cure for cancer, solving a crime, researching the great American novel, building a house, or designing the next killer application, your wisdom is vast, Master 5. Just be careful you don't trip that nerd alarm on your way to the Nobel prize. Other 5s who share your creative bent? Georgia O'Keefe, Isaac Newton, and Stanley Kubrick.
