You stick to one place. You don’t change your job, as if you have married the workplace. Changing jobs feels like a new challenge; it involves a new environment, new people, new tasks, and the word ‘new’ brings a strong feeling of uncertainty to you. It’s a maybe to you—maybe I will fail there, maybe I will not perform well there, maybe I will have to act differently there, maybe I will have to learn different things there. And the focus in all those maybes is on the worst possibility: It won’t work out.
