Got this tip from a business mentor of mine:

“If you understand the technical work of a business, you understand a business that does that technical work.

And the reason it’s fatal is that it just isn’t true.

In fact, it’s the root cause of most small business failures!

The technical work of a business and a business that does that technical work are two totally different things!

But the technician who starts a business fails to see this…”
