I plan as much as possible. I keep everything on the computer. I usually make a few mistakes. When I get back from my tour, one of my first tasks is to write a "Memo to Myself" about the trip - what went well, what didn't, what I forgot to plan, what I would like to add or subtract to my packing list in the future, etc. I have a bunch of these so for each new tour I just refine my planning; I don't have to reinvent anything.

I don't have to worry about my house. I have family members who don't go on the tours with me, so they take care of everything. I have my wife email me with the amounts of all the bills that come due. When I get to a library or other place with internet access, I open the email and pay all the bills via my bank's online billpay service.
