There's a tradition that anyone seeking to convert to Judaism must be turned away 3 times. They are told only about the possible negatives. Only after they return the 4th time have they shown that they want it badly enough to be taken seriously.

Sometimes I think the same approach should be used for starting a business. OP sure tries awfully hard to emphasize the possible negatives. Hopefully, most hn readers want it badly enough to remain undaunted and keep coming back for more.
