This is a great question. I don't think mentoring features nearly enough in our line of work.

Guiding early-career engineers is something I am sure many of us seniors have done (I'm 25+ years in to my own career), but for people like yourself with 10, 15 years+ I do feel it's hard to find such guidance on "what next?" and "is this the right path?", and someone that can help one navigate choices which might become available.

Perhaps a professional life coach? Although I have never done so and cannot recommend or discourage, it might prove completely fruitless...
