A decade of mistakes I wasn’t wise enough to learn from others guides my New Year My father always said that a wise person learns from the mistakes of others. But what happens when you don’t know anyone who made the mistake you’re about to make, and you don’t know you’re about to make a mistake? When I hired a flooring company to install solid strip hardwood flooring in 1998, I was not yet working in the flooring industry. How was I supposed to know to ask about the chemical emissions that would fill the house when they finished the floor with a toxic, oil-based polyurethane? Okay, some people would argue that I should have investigated when the installer mentioned he had liver damage, and assigned the cause to his profession. He did not expound about finishes or less-toxic, water-based options. So, I assumed he was talking about a different liquid all together.
