> For some entrepreneurs, the toughest part of a pivot may be setting aside their personal convictions-and egos. "It's very hard as an entrepreneur to move away from your core idea," says Phumbhra, of Chegg. "But if your customers are telling you to, you have to learn to be flexible."<p>My experience has been that many founders are contrarians with a grand vision, which can make a pivot towards a mainstream/less-grandiose direction particularly hard to decide to embrace. Has anybody else noticed that a founder is often the last person at a company to embrace a pivot?
