I decided long ago that for me to be fully self employed, I would either need to make 3x my current salary or have no other immediate options. Currently the only consulting I do is via retainers to mid-sized businesses, where I average 5 hours of work a month, get paid for 10, and occasionally go over when necessary. I am not immediately on call for anything and my clients are aware that I have a day job that takes precedent. My rate for any additional clients is also much higher than my rate for existing clients. It's what my extra free time is worth to me.
