Get a smartphone. If you’ve ever showed up at a canceled class or missed out on a cool event because you didn’t check your e-mail, you’ll understand why this is one of our new rules. Senior marketing major Jennifer Russey said most people in the Kelley School of Business own smartphones. Her one rule for students: check your e-mail at least once a day. “Kelley is always going so fast that if you’re not going with it, you’re holding other people back.” Sub-rule: Don’t text (or e-mail) and walk. It will lead to some kind of awkward, public humiliation like running into the bike rack outside of Ballantine. CJ Lotz
