This notion puzzled me for some time: Have you got X years' experience [cooking, programming computers, running a business], or one year, repeated X times?
Simply, have you grown? Are you doing something new this year, something you couldn't have comprehended X years ago? Did you acquire a new skill, learn a new point of view, make a new friend, visit a new place?
If not, you're on the hamster wheel. Time to bail out.
