You have been blessed with exceptional gifts!
Your ability to distill and communicate your knowledge is really remarkable, and it far exceeds most of your peers. Your skill is on par with the really exceptional textbook educators (that routinely charge $150-200 for their books). Your SSIS Stairway series was exceptional. (I printed the series and had it tape bound.) Have you ever considered expanding your communication skills to distilling the BI Semantic Model??
For me balance is an overrated luxury that I can't afford. I am in my late 50's and I am reinventing myself. Given the diminished runway, I am relentless in studying my craft.
