I find it hard to believe that your discipline and professionalism doesn't come from, or go hand in hand with passion. Or maybe you are passionate about being disciplined on itself?

Sure. I'm passionate about turning off my computer at 18:00. And I'm passionate about not hurting our customers. These two go hand in hand: I work very hard to avoid prevent doing things that are likely to cause incidents, as those hurt customers who are not at fault, and they often mean I have to stay late.

I guess you could say I'm passionate about testing and observability, though that doesn't really describe how I feel. It just puts me in a sour mood when something breaks and we could have prevented it with better practices from the start.

Is it that hard to believe that certain people simply have the skill to apply themselves? That's what discipline kind of is.
