(Wall Street Journal) — Last month, Brandi Greygor did the unthinkable for an entrepreneur just starting out: She took a weeklong vacation. “I needed one because I ran myself into the ground,” says Ms. Greygor, a 35-year-old mother of two who also works part-time for a consulting firm from her home in Union, Ky. But it wasn’t easy separating herself from the retail business she launched last August to supplement her income, Sassy Mama Boutique. “My worry was that I’d get orders in when I was away and not be able to fill them,” she says. Whether you stay at home or travel, taking a vacation from building a business is critical, experts say. Entrepreneurs tend to work intense, long hours in the beginning and can easily burn out fast. Besides, deviating from a normal routine is an opportunity to think about an enterprise from a fresh vantage point, which can be helpful for deciding which direction to go in next.
