Somebody once told me, "Entrepreneurs are quick to make decisions and slow to change them."
I agree with this. All too ofter, I see people changing up their course of action, without giving things the proper time needed to actually work.
For example, one week they're be working on Ebay, while the next week they'll be doing something with Google Adsense. And the week after that? Who knows?
With that said, I think it's important that you find a business which is a good match for you. This should be fun, so you want something that is both enjoyable and fits into your schedule.
Over the next month or so, I'll be posting information about various ways to make money online. If you're looking for a good "match" that will both make you money and be enjoyable to do, I hope you find this information helpful with making that decision. But if you're already working on something, please don't let what I'm saying detract from what you're currently doing. If you can work it in your current business model, use it. If not, skip it.
To summarize... Let's say I post some things about Ebay. Can you sell your current product on Ebay? Or, can you create or license a new product quickly, which will allow you to generate leads for your current product? If so, do it. But don't drop selling apples via your own site to sell oranges on Ebay.
