My solution is... make freelancing my business for awhile (it sometimes works), and it's sort of it's own business, but I still answer to the clients (the boss), I use the money from feast-cycles to buy me time to work on side projects/SaaS ideas. If the side-project thing never works out, I'd like to turn into an agency, and hire other devs to do the dev work and move more into project management and running the business.
