VCs are optimizing for the unicorn, and there is nothing wrong going for the non unicorn either. It's just you shouldn't go for VC financing. If you make a business that hires 50 people and throws off $10 million a year to you, you'll probably make more than most founders ever will anyway after 3 years of that business.
I have a pal who made a Unicorn. He got a nice condo out of it! His next one was a non-unicorn and he made vastly more when he sold it, as he had most of the equity.
