Wow, what a tough question.
Outside of the actual time I've spent (wasted? invested?), my life is objectively better for having found DDF. Between F class tickets, experiences, business opportunities, and friendships, hard to say otherwise.
That said, I wonder if I had taken all the time I've spend on DDF/DDMS/travel/churning/etc and focused it on something else if I would have been even more better off...
