Ready to quit your job? Know what you are getting into when you take the plunge. The best advice I can give is to start building multiple (somewhat) passive income streams right now. For instance, I could not make another update to any of my apps for the next year and most likely continue generating the same income. Whether it's an book, app(s), video course, blog, or a weekly newsletter, find different sources of revenue to smooth out the times of freelancing famine.
