As the owner of a small business you are literally the key to the whole company. You provide the inspiration, the final say in business goals, and the raison d'etre.
You might think the most important business strategy is to maximize income or efficiency. But really what's most important is keeping the heart of the business going strong. That means you.
Work burnout is a real risk for small business owners who put more than just their time and money into their companies. If you want your small business to succeed, and of course you do, make sure that work is always a joy and you're excited to come back and do it again every day.
