Earlier quoted context omitted.
I'm the same way in a lot of respects. I'd love to wake up every morning to tweak a product or SaaS business that I live off of but I haven't gotten that spark from anything yet. What language(s) do you work with?
Work with or are competent at? :) For the last 8 or so years, the jobs have been C#/.Net. Before that, Delphi. Before that, C and C++ (quite a while ago). There's also been a touch of Ruby, a couple days of PHP, and an odd smattering of x86 assembly.
Best of luck in your search.
