I keep being reassured, but this still alarms me:

“If you become too indispensable to a specific project, then that is likely to be your project forever. If you get bored with that project, too bad. If you want to learn new, saleable expericence in case something does happen to your job or to your project, too bad. I can understand not wanting to move into management, but if that is what you want, too bad. Finding one particular job that you want to stick with is great, but it could become an albatross around your neck.” [Excerpt from Considered Harmful]
