I was there at about 10 years, now after 12 years I'm happy again because I realized that when I was happy it was because I was ignoring the corporate politics, the unfair promotions and the bad work ethics. Now I learned to be vocal about it when it impacts me and delegate the responsibility of fixing it or giving feedback, and ignore it when it doesn't affect me... maybe give a heads up there, like, "hey maybe they are just spewing bullshit to keep you busy and really need to solve some issue between them! be careful!" and then get back to what I need to do.

Yes my work now as senior whatever or whatever whatever manager is not as easy as Jr. Sysadmin, but it's rewarding if the organization is functional, once I learn the ins and outs and after figuring out what to worry about and what to not worry about.
