Starting a small business is hard. Keeping that business going is even harder. It can feel like an endless wave of decision-making, strategizing, and to-do lists that only seem to get longer. Fortunately, you’re probably not the first person to start the kind of business that you’re running. And even if you are, you certainly aren’t the first person to call themselves “entrepreneur” and dive into the start-up deep-end. That means you don’t have to go in it alone. There are people you can turn to for advice, support, or even just a kindred spirit to talk to. These people are called mentors.
