You can't be passionate about boring work 24/7 and most jobs are boring work. Even if they aren't when you start, once you've done something 1000 times it becomes rote. Why do you think there's stories of burnout from places like google where people join up to do great work, but get stuck doing CRUD apps to support the business?

The only people I see claiming everyone needs to be passionate all the time are business owners and management who then channel that passion into unpaid overtime
