I agree that it can be valuable.....if you want to continue the corporate life. But if you don't want to be a "suck up" for the rest of your career, MMM principles can help free you from it IMO. I was a highly competent project manager for a top financial firm, and consistently received high reviews for my abilities both from my supervisors and from our internal customers. Yet, when a new management team was brought in, and our departments were restructured, and my bosses were reassigned, I was one who was not retained in a round of cuts. The word on the street tells me it's because I was too good--I was a bit of a bulldog in getting things done. I felt bad that I had not done more with "relationships" but in retrospect what I wish now is that I hadn't been greatly in debt so that returning to the corporate world hadn't been a requirement. In other words, I wish I had known about MMM in those days.
