Heya Irataages, I'm sorry you are experiencing a bit of a brain scramble. I am honestly the last guy that is qualified to dish out some advice on management and organization, especially considering the fact that I can barely maintain a balanced array of relaxation methods. I just don't know what I should do first, play Castle Age, or work in the yard lol. I do however sympathize, and wanted to at least try to help you find an answer since I have seen a few programs that are at least worth looking at. In fact, maybe you really don't need a program per say, but just to learn a few tricks that busy people use unconsciously. I can hit you with a series of links that I found to be helpful on a very fundamental level. Try not to laugh at the first one, its primitive but you'd be surprised how even the most intelligent of us can overlook the really basic areas we could apply some effortless change to.

This covers organization on a basic level, that gray area that we skip over in favor of looking for a personal secretary as you put it. I would actually benefit from this since I'm about as organized as a 12 year old kid's room. it goes into looking at how much time you have to look at and develop your organizational skills, where you need it, and where the chaos is stemming from.

Here's another one on home office organization. You may or may not have a home office, but given the kinds of success you have shared with us about your experience with Pampered Chef, you probably need one now. It doesn't have to be much, even just a desk with a bulletin board you can tack things onto will help out a lot. My fiancee would be lost without hers. The article gives you tips on how to organize your home office, so now that you have this article, make sure to go get an office lol..no seriously.
I see you have a computer obviously, or at least access to one since you visit us here on Repspace. Is it a desktop or a laptop? I'm a gamer, so life isn't normal if I don't have a desktop with an HD monitor and a $400 graphics card pumping out frames. You on the other hand, you don't need much to apply a PC to business. Some storage drives and programs that handle your finances, calendar dates, inventory, whatever you have to worry about would be ideal. I don't recommend more than one program, many of them will do all of it for you. I actually get by on 1 single time sheet each week, and it took me weeks to get used to a simple Open Office time sheet doc lol, and I STILL fill it out with tons of screw ups. If you have a desktop, get a cheap but reliable laptop, a few zip drives and if necessary, an external hard drive to back up your stuff. Try Dell, or Gateway, which makes me cringe to say because I build computers and my monsters kick the crap out of anything those companies can give you any day, BUT, they do make the technology affordable, and again you don't need a supercomputer to run a business.
Last but not least, you can always try network marketing forums and ask for advice....hah, just kidding, although it was a smart move. I can't really recommend any particular software aside from what I find on a search engine, because I don't use any, and again I'm not qualified to say what works and what doesn't. I wish you well though, and I hope you find exactly what you need, and that my babbling helped at least a little.
