Just make sure you've never left a job in under 10 years, even if you got an enormous raise or your boss was an ass or you got a much better situation out of it. In fact, you should be willing to tolerate a shit situation and lower pay for years just to prove your loyalty.

ps -- make sure never to look out for #1 -- that's for companies, not you, silly employee
