Getting fired is stressful, granted. The trick to not being stressed out about getting fired is to expect it every day. Work toward it. Be willing to say the thing that might get you fired, because if you’re not, then you’re holding back. Otherwise, you’re giving the answer you think people want to hear, or the answer that you think saves your skin. That’s not the job. Your job is to design things the right way, the ethical way, even if it gets you fired.
