I personally have zero desire to be a manager. It could be a function of the experiences that I have had with managers that I have worked for currently and in the past. While there is a large salary increase to be had at the manager position, it comes with a tremendous amount of responsibility and pressure. Not only is their pressure from above (higher level managers and C-level officers), but there is also the pressure of dealing with individuals and being responsible for their growth, output, and security/stability. As I mature, I am sure my feelings may change, but as of now, I think I would be content with attaining senior level engineer status. Making me an expert in my area of application.
