That's a great idea, Jacque. Also, set aside one or two days per month to get your tax info in order. I keep a running spreadsheet so that, when I "feel like it," I take backed-up receipts and input all the information into the spreadsheet. That way, I don't have to do it all at once to pay quarterly sales tax, nor do I have to freak out and look in 15 places for all the receipts and then add them up to do yearly.
Keeping track of ALL tax info per quarter, and not just income, is a great way to take some stress off that paperwork every year. I also file in early January, so that "tax time" doesn't mean anything to me! It's the best stress buster! :D
Also, I'd give myself way more than 1/2 hour for lunch. I'm Latin, so I have to have my siesta! Make work FUN and COMFORTABLE for you and your style of living. Being organized and self-managed doesn't mean you have to be your own sweat shop!
Good luck!
