Angel investor Mike Maples talks in this video about "pivots," those gut-wrenching, desperate changes in business model that entrepreneurs sometimes make when things really aren't going well. Sometimes a beloved idea has to be abandoned or modified in serious ways to get to a larger business.
Pivots are really hard and painful to do, without a doubt. They aren't planned, they weren't intended or foreseen. But sometimes it is the difference between huge success and middling along. Pivots also are risky. They are emotionally hard to do, since it often means abandoning a dream.
