I say this all the time:
"When I'm sick of publishing, I'm going to..."
Sometimes (because I have decided that "pipe-dreaming" is an completely acceptable hobby) I get very detailed in the planning. And sometimes they're completely silly.
Here are my schemes:
-start a summer day camp for 12+ (who don't have day camps available to them anymore) to teach them how to sew.
I'll use my church's fellowship hall (affiliate with them); partner w/ sewing-machine & fabric stores (or repair places) to get them publicity and some sales in exchange for help w/ equipment and supplies and field trips; round up used machines or ask the students to bring their own (so they get used to using them); set up and break down the tables (kids can do it!); start off making kids' clothes (to send to the orphanage my church sponsors) since they're smaller and go faster; take them to the Y twice a week to go swimming.
-move upstate and start a pedigree mutt breeding business.
I'll select my dams and sires for traits like: house-trains easily; healthy, long-lived stock; good with kids; very loyal; barks/doesn't bark. People will come to get a dog because they want one of those traits.
-Start a company called The Handy Housewife.
I'll have to move to dense suburbs to make this financially feasible. People will sign on and pay a retainer that gets them a guaranteed half-day stop each month, in which I do things like sew the fringe back on the rug so it doesn't get worse, or oil the hinge, etc. We'll assess whether they need bigger jobs or not. If so, I'll round up and supervise the plumber/painter. I can cook (or be the caterer's assistant for your dinner party), clean, sew, paint, put up shelves, do basic handyman stuff, and supervise your more skilled pros. I'll probably have to round up some other people.
I've got the truck all planned out--sewing/household supplies in one section, tools, etc., in the other.
I'm going to write an iPhone/Android app that my clients can use to send me handyman/housewife stuff the moment they think of it, and I can review before I head over to their place so I can be sure I have the right tools, supplies (paint color), etc.
What about you?
