I usually have a reason for breaking rules. As for calculated reason I can say I like "hacking the system"
Sometimes it's just impatience though. I do get irritated if for some reason I'm forced to play by rules when I would rather break them for my own goals. In other cases if it doesn't get in the way I'm just indifferent about rules. Well and sometimes a rule can be used to get the advantage so then in those cases rules are useful
As for IDGAF, well that too, I sometimes break rules where it would really take minimal effort to go by the rules and when other people comment on that I tend to be all about not giving a fuck, I do think to myself or even say it out loud sometimes that they're too much of a pussy.
Oh and what I really hate is when someone tries to use Fe-like reasoning for certain rules.
Yes I'm too impulsive for my own good with some stuff. But I've also learnt to sit on my ass for pretty long to do a task if needed.
