To successfully run a business on your own, you need to ensure that you are free from many stressful situations as much as possible. In that way, you would focus on more tasks and reduce the risk of mixing your business and personal finances. As an entrepreneur, you must learn the importance of living within your means, especially in the developing stages where cash is tight and stress is through the roof. Stay clear of tacking on personal debt and instead focus on staying profitable and incurring as little risk with scale as possible. Personal debt and debt meant to fuel a risky business can work, there's sure to be thousands of stories about it, but starting small and scaling fast can be a much safer route to do the same while learning potentially costly mistakes for pennies on the dollar.
