Honestly, you don't have to.

Getting cancelled doesn't just cost your job, it also costs friends and family and possibly your spouse as well. So even if the probability is small the consequences can be so huge that any person prone to anxiety won't be able to live with the risk and instead just changes their behaviour to avoid it. And when anxious people don't they just commit suicide when it happens, making the effective consequence death, avoiding that at all cost seems reasonable.
