re: Moving job to job

I think when you're young there's nothing inherently wrong with it and it could be a great way to advance quickly. Frankly, you should do a little exploring career-wise right after school.

That said, you do need to "settle down" eventually and plan to stick around for a few years if you can this time. You'll be in the "five years' experience" group pretty soon and employers will want to know you are worth some investment beyond just your salary.
