As much as I want to agree with this, what I've found happens if I do a particularly good job is... more work. More projects. I have "bandwidth" available to help out in new areas. When I left my last job my manager and I put together a spreadsheet listing all the projects I headed, and it was something like two pages long in excel. Everyone who saw it had their eyes bulge at the size, and I left because I was being really overworked.
But god damn it, the only reason I want to work hard is so that I don't have to in the future!
I'm seriously considering leaving tech because of this.
