According to the source, entrepreneurs are most stressed by excessive workloads and financial issues. Many worry about making enough money to meet payrolls. A number of them also fear that they don't perform well enough to meet customers' expectations.

To combat these issues, the Wall Street Journal says planning has proved the most effective method of stress relief. It's good to take time to revise or update business plans in the changing economy to avoid feeling directionless or overwhelmed.

By stepping back to plan, small business owners can find temporary escapes from the daily grind while also creating a long-term focus for their businesses. The source advises going on "mini-retreats" away from the office to evaluate how the business is performing and to set goals.

These tips on reducing stress could also help bring positive energy to an office. This is especially important as the Guardian Life Index reports that motivated staff help draw consumers in economically trying times.
