I am an advocate for knowing the numbers of your business. Ask anyone who has ever experienced any kind of success in this industry and they will tell you that understanding their numbers played a large role in that success.
But I am not a fan of business owners who try to become too many things above and beyond being the owner of the company.
Some people call this “micromanagement” – trying to control or be a part of every tiny little aspect of the business.
Keep track of your numbers, review your numbers, make decisions based off your numbers but quit trying to learn the tax code. Save that headache for the bean counters that you pay a few times a year to ensure compliance.
