The intent behind this questioning is the important thing. In an evolutionary context, the work you're doing is like an organism that is adapted to some degree to its business niche. You may be able to strike out on your own by making a business 'better adapted' to the same economic niche through changes in the technology/skills used. Alternately, you may be able to find a niche that better supports the toolkit you presently have to work with. This is the simplest way to generate innovation but it will likely not produce results that are the best for your overall happiness.
For that, you'll have to determine what kind of niche can support you financially and which you personally are well suited for. From there, it's a matter of figuring out what adaptations in your personal skill and technology set are necessary to transition you over to that niche from your existing job.
