Exactly. People who've always been employees often forget that they're actually being paid for doing something very special that brings value to the company. And that this value has a cost, which is why they're been paid in the first place. Not because your boss likes you, or that you've got a great resume.

I would recommend everyone to spend some time freelancing, even on the side. It completely changes your relation to your work and your client/boss. In a very positive way ( less thinking about affect, more about skills and value).
