How many online revenue streams do you have right now?

One? Three? Ten?

If you have less than five, you need to get going on some new opportunities -- you're simply not diversified properly.  Losing a couple of your existing sources of revenue will cripple you financially, and the best way to avoid this is to start up a new source each month - 12 per year.  If you hold yourself to this, the probability of being crippled financially by losing one or two of your revenue sources goes down dramatically -- the other 10 will still be going strong, and if you've been doing this for a couple of years, the other 20 will more than make up for the loss.

So the next question is "How am I supposed to come up with a new income source each month"?

Here are some ideas for you -- Digital Information Products, Affiliate Sales, Physical Products, Consulting, Services, Coaching, Google Adsense, Yahoo Publishing, and PeakClick.  Each of these categories can provide multiple income sources for you, so get started!
