Where do you want to go? It sounds like you are implying you want to get back to the technical work? If the job does not allow, then you may need to find a role. Or is the concern that you are losing touch with the current tech and can't make technical decisions like you used to? Or are you asking what is the next step as a technical manager?

If you feel that you aren't good at anything (which clearly is not true given that you've fostered your team) then what is it that you want to get good at?
