You might be giving up on projects too soon, or you're not thinking hard about the market potential and income options.

It's hard to "start" a company, that's why it's better to keep all your resources and retool or specialize on a certain direction as the market dictates.

Or you might just be calling the wrong thing a "startup". Software developers might be prone to this error, thinking of any application project as a business (note the multitude of "iphone startups")
