You have family-owned businesses that have been around for 500 years. You cannot name a corporation that survives intact for even a few decades.

If you have more than one reason to do something (choose a doctor or veterinarian, hire a gardener or an employee, marry a person, go on a trip), just don’t do it. It does not mean that one reason is better than two, just that by invoking more than one reason you are trying to convince yourself to do something. Obvious decisions (robust to error) require no more than a single reason.

If you're going to fail, you'd rather fail early than fail late in general.
