You can't keep a good entrepreneur down. In fact, they're more optimistic now than they were during the tech boom (or at any time since 1986) leading some economists to forecast an upswing in growth in the third and fourth quarters. The turnaround in opinion is remarkable: back in March when the war began, only 7% of the entrepreneurs surveyed expected the economy to improve in the next six months. The optimism survey is conducted monthly by the National Federation of Independent Businesses.
