what type of online business is the best?

I chose Network Marketing, or MLM. I chose this for a number of reasons, the biggest one being LEVERAGE, and the ability to help others to achieve their success. and Another good reason is because it can be both online as well as offline. I use a very good system, that is generic and very duplicable that teaches the skills you need to succeed online and off, with MLM, if you would like to know more about it, please let me know. I also agree with Workingmom50, get multiple streams, though I also believe strongly in focus, work on one, until you have it down to a science, then once you have a regular income, that you can easily get with minimal daily effort, then move onto the next stream. Sincerely and With Appreciation.

I can't really choose on any of it. As long as I earn, I'm good with any of it. Tha't what I think.

It depends upon your interests and ability...

It depends upon you. It depends in following things ==Yours ability ==Time that you want to spend ==Income that you want per month ==Yours Interest etc.
