I've had some great bosses, and not-so-great bosses. But I tried to learn something from each job I had, and build on my skills as I went along.
So many people would feel so much more secure if they had more to put on their resume than just a college degree, which says very little. An actual certification would look so much better and quite a few from diverse areas would look even better. I say that people should diversify professionally with their skill set and they’ll be just fine in the long run.
