The goal is to personalize these parts so they're your own. By all means I encourage people to pick their own but boil them down to succinct things you can describe in an elevator pitch.
They're very powerful when you talk to a manager or a potential employer about what makes you happy as an employee. It can be hard for a manager when you ramble on about what you want but I can blast these out along with a short example of each and use them as the basis of a productive dialog with the person I'm talking to.
In short, yes, pick your own, but know them cold and know how you measure them and how you can communicate to others when your not at a 5 in every area! :-)
