I believe one of the biggest barriers to personal advancement is self-perception, in particular, the difficulty in imagining yourself in a role that is not your current one or some version of it within a company or industry hierarchy. For what it’s worth, I’ve managed to enlarge that self-perception and change jobs by a) asking good friends and professional colleagues for their honest views on what I’m good at and where my shortcomings are and b) networking outside my professional circle to understand how my role is perceived in terms of what constitutes success (personally and for a company) and how others succeed in non-engineering (e.g. sales, management) roles. You will probably be surprised at the answers and, I hope, see that there are many more options out there for you once you see yourself as more than just your job title.
