Once you assess someone thoroughly, check references, and decide to hire them—you also have to decide to trust them. You can’t start with zero trust and expect someone to prove themselves to you. Whenever you’re embarking on any journey—a new employee, a new job, a new partnership—you have to believe it’ll work. Believe that people will do right by you. Of course, there will be disappointments—some people will knock your trust down to 90 percent, to 50 percent, to zero—but if you let that keep you from trusting others, you’ll never know the relationships and opportunities you missed.
