>>> I’ve since learned that even if you are good at your job, it will not magically get noticed. You have to be a full on advocate for yourself at all times and basically shove your work in the face of your boss or else they will think you are doing nothing.

Absolutely! You need to make a big deal out of every little accomplishment and every tiny bit of work you do. And make sure to do it frequently, like every meeting, every week, every one on one. You never stop selling yourself. Otherwise, they're just going to assume your sitting around twiddling your thumbs.
