After developing professionally for over 20 years and as a hobbyist for 10 years before that, there is nothing "exciting" about software development. I don't hate my job or my career by any means, but at the end of the day, it just funds my lifestyle.

That's fine, but plenty of us choose to work on systems we find intrinsically interesting and/or on problems we consider important. Sometimes that comes with a financial penalty. Personally, I'm happy to get slightly less money in exchange for more interesting and meaningful work.
