The risk of relying on a handful of customers is not just financial. Your product also is at risk when you're at the mercy of a few big spenders. When any one customer pays you significantly more than the others, your product inevitably ends up catering mostly to that customer's specific needs.

Who you work with is even more important than who you hang out with because you spend a lot more time with your workmates than your friends.

Hiring people is like making friends. Pick good ones, and they'll enrich your life. Make bad choices, and they'll bring you down.
