You’ve weighed the pros and cons, and after careful consideration you’ve decided to make a big career move — quit your job, change industries, or go back to school. You know it’s the right choice for you, but your friends and colleagues aren’t convinced. How do you persuade the people you respect to support your decision? First, consider their motivations. Most people think they’re being helpful by playing devil’s advocate, but it may be that your move has them questioning their own career choices. If it seems like they’re projecting, take their advice with a grain of salt. Second, really listen to their concerns. Those close to you may be right to express some hesitation over your career change. Assure them that you’re taking their advice and objections seriously. Lastly, emphasize that this decision is ultimately yours and that it’s you who has to live with the consequences.
