Good, sounds like you've got a good plan.
I contemplated "starting my own business" (freelance writing/editing) before I took this job (the job announcement came the week I retired but it took three months to hear after I sent in my resume), and honestly, I was freaking out. I am NOT cut out to be an entrepreneur. Too many details to worry about. I much prefer to show up, do my job, and get a paycheck with benefits. Everyone is different. Some people find being their own boss freeing--for me, it would be an unending source of anxiety.
