Most men buy dress shoes with glued on soles and top-grain leather even though full-grain leather welted shoes will last 5-10 times as long for 2-3 times the price and often less than that. A good $200 shoe brand is a much better value than most of the $130 shoe brands.

Most companies still conduct interviews when hiring employees; unstructured interviews to boot if the person hiring isn’t from HR, but the best evidence suggests interviews are mostly useless.
