I stumbled across a 10+ year old article from Seth Godin about getting too competent in your work. It’s a great reminder that getting really good at something can stop you from changing into what you need to be.
Do you work for a competent company? A company in which people are hired because they’ve done a certain job before, in which the upward path is slow and the sideways path is nonexistent? Such companies are especially frustrating to the internal (or the external) change agent.
