I've just been thinking about this "numbers game" concept again, and can see how it can be problematic. 

If you put your ad in front of several hundred people, then chances are someone is going to buy something.  Similarly, if you come up with many business ideas, surely one of them is going to go gangbusters.  So, the challenge is to just focus on that, and perservere with it until it works.

This is a problem for me.  I've got all these little projects going already (blogs, flyer delivery, affiliate program marketing, etc).  But rather than just focus on one of them, I keep dreaming up new ones!  So, I'm still struggling. 

Maybe I've got a kind of ADD?
