Oh Don I so get you I am in the same boat as you so I am not sure if I can offer advise but I can say I am trying to do more for myself and so everyday I aim to do one thing that will give “me” value I treat myself as if I am a client and see if I have help my client that do to achieve their goal.
As for selecting a niche how about working backwards from where you want to be to now. For example I want to be able to in 5 years time be working with xx people and solving this problem with them! No much but a start 🙂
