1. The Time Is Right to Borrow

According to the Thomson Reuters/PayNet Small Business Lending Index, which measures the volume of financing to small companies, overall borrowing rose to 115 in March from 111.6 in February--the biggest monthly gain since December. Moreover, a separate index released by PayNet showed loan delinquencies of 31-to-180 days ticked up to just 1.48 percent of all loans made, which is only slightly above record lows.

5. The Real Cost of Business Travel

According to a new study that surveyed 7,400 global managers, the consensus is clear: Business travel is extremely stressful and mentally taxing.

Think about that the next time you ask an employee to get on a plane.--HBR
