Though most successful entrepreneurs are workaholics at heart, it’s important not to sacrifice all your time outside of work in service of your company. Humans are social creatures. Regular connection with our friends and loved ones is a vital part of a healthy life. With that in mind, set clear boundaries between your work and personal lives and stick to them. The easiest way is to take the same approach to scheduling quality time with your kids or old college buddies that you do with your business — put it on the calendar and honor the commitment.
