I've always been interested in new and different ideas, especially ideas about making money.
Even as a kid I had my little money-making projects: picking wild berries in the woods in Maryland, putting on a magic show for the neighborhood, collecting pop bottles for the deposit, pet shows, lemonade stands, newspaper route; stuff like that.
I still enjoy doing things that are just a little out of the ordinary.
These ARE some pretty good advantages of working at home. And it's true, as these replies point out, that some of these advantages could also be disadvantages, like whether there are more or fewer distractions, for instance, but that could be a different thread "The DISadvantages of working from home." That could be a potentially useful post, really. (When you are your own boss, sometimes your boss can be a real SOB! lol)
However, since this is about the advantages...
I think one of the advantages is that you have to learn to deal with the potential disadvantages, that is, you have to develop self-discipline. With nobody coming around to remind you to do things, nobody to tell you what to do and when, you have to develop your own self-guidance and responsibility, and those traits are going to serve you well in all areas of your life. People who have never had to do that, those who are told when to be where to do what and how - those people are missing out on a lot of the important elements of learning to live, in my opinion.
Another advantage is that you can get along with fewer resources. Yes, yes, I understand that means you have fewer resources to use, which can potentially be a disadvantage, but like I said, that's a different thread. What I mean is that by needing less, you are more free. When you can get along with fewer expenses you are not driven so much by a feeling of necessity. As Epicurus said "Nothing is enough for the man to whom enough is too little." By needing less, I have more time available to pursue what means more to me and life is not so much a rat race.
Working at home means I can bake my own bread, working at my desk while the dough rises. I can cook beans for hours. For me, this is an advantage.
Working at home makes me feel like I'm in charge of my own life. I consider that a huge advantage.
It is fun to sell things on eBay, and to get started you don't have to spend much money. It's not like you have to have a whole truckload of things to begin with, is it? I generally think it's a good idea to avoid getting any kind of loan if you can possibly avoid it.
What kind of thing do you want to sell on eBay? I used to sell out-of-print books there, and enjoyed doing that for a few years. I started with just a couple of books that I bought for a dollar or less at thrift stores. The key to that kind of selling, that is, to selling collectibles, is knowledge. You have to know your field, know the kind of things that are worth more than what the thrift store is charging. In my case I specialized in used children's books, books about business, and books about obsolete (or "legacy") technology (books about steam plants, for instance). My point is, if it's something that you know about and are interested in yourself, then you'll be able to recognize things that you know others will want, and then you can pick them up at thrift stores, garage sales, auctions and so on. When you sell like that on eBay, you don't have to have more than a few dollars to get started. In my case, I was sometimes able to buy a book for a dollar or two and sell it for $200. True! Well, that didn't happen often, but it did happen a few times and that was quite a thrill!
SO... the question is, what sort of thing is it that you want to sell on eBay?
