I'm only 30, but I feel the same way. I've just never been interested in keeping up with the latest tech, I just like to get things done with the tools that work. PHP, JQuery and WordPress still work. I'm a generalist as well and have held positions or have done a fair amount of work in most areas of marketing in my 9 years in the industry.

I think your idea of teaching and doing corporate training is the right direction. You could then take your lectures and record those and build courses on those. That's how you create that content-momentum and spend less time building, thereby improving your ROI.

Good luck!
