Knowing your options and determining potential risk to your backup plan isn’t paranoia.

My car already has the few things I need in the trunk. All I need to do is check the weather and choose what clothes to wear. Having a road atlas for the entire United States means I can navigate without a phone. (Which has happened.) Having an extra hoodie and a pair of old boots means I can walk several miles in snow.

All of these items have been used or badly needed the past.

If I was starting a company, I’d do similar things and I wouldn’t worry about failure and would take risks, even serious ones, with confidence.
