It does require some ongoing marketing efforts for any person to generate, build or sustain a business. Business is “good” more or less due to successful marketing, word-of-mouth and other referral. Freelancing for another firm or business, considering that you’re a work-for-hire with them and thus representing their company (unless you can get some release to use work you’ve generated for them as samples and demos for your own business promotion/marketing) you really don’t have the opportunity for “switching when business is good” because it won’t be YOUR business, it’ll be the group you freelance for.
As I say often and loudly, you can have a business, established services and products, a website, experience and samples or demo material, but none of it will matter, freelance or independent businessperson, if you don’t market consistently and persistently.
