Focus on enjoying the people you work with and spend less energy thinking about your work. Stressing over work is a fool's game unless you have skin in it.
I had a pretty low point in my career and I simply changed my focus to collecting as much money from the wealthy bosses as I could while providing as little value as I could. After all, that's what they're trying to do on the other side of the relationship.
Now again, what I have said is easy to grok and enact once you've had some success. I don't advise this attitude for folks just entering the industry, but after 5-10 years you'd be amazed at just how valuable you are, even when not really working too hard.
