Jay Goltz writes that talk of a double-dip recession is scary but doesn't have much effect on his business decision making. Most business owners have done all they can to survive after the first downturn, including cutting staff and expenses, and there's little left to do if a second dip hits, he writes. He recommends business owners take calculated risks. "Owners need to figure out how much risk they can take and still recuperate if things get worse. Avoiding all risk in business, ironically, can be more damaging in the long run," Goltz writes.
