An obstacle race across ten or twelve miles of mud, with water cold enough to take your breath away, becomes the argument against testing anything with a toe first. Devin Hunter uses it that way, and the post concerns fear rather than endurance racing.
He is honest about his own route. A travel company where he had no idea what to do, more than a decade after an earlier attempt, and no marketing training behind either of them. That admission makes the beginner posts land better than they otherwise would.
Nothing else here comes close to the video post for usefulness. Ask customers for a minute of feedback on camera, interview them if you want more structure, and record a demonstration of the product, all of which sits inside what a small business can actually manage.
There are pieces on habits and on being a father at home.
Take the video post if you have a business and no video.
