A couple ways to make a million dollars:
1.) Sell one $1,000,000 product.
2.) Sell 10,000 $100 products.
3.) Sell a million $1 products.
There are other ways, but some thoughts:
A.) Number 1 is the easiest. Selling to a few people with big budgets and lots of problems is the simplest of any scenarios listed above.
B.) Number 2 is the most fun. Well, as a marketer at least. Getting 10,000 customers means earning fans, making something worth talking about, and making meaningful connections.
C.) Number 3 is impossible. And getting more so every day. This is a good thing.
