I used mostly Windows systems primarily and I guess I just adapted that habit of having an Administrator account for when shit goes down, and my own user account that has admin rights.

It's just convenient. I liked my Administrator account as clean as possible, and I do the same in Linux with root. There is its time and place where I need root.

But you are right, I should change my habits. I'm not even sure how sudo and rights and environments and sessions and god knows what works exactly behind the scenes, so probably, maybe, there are technical differences too in the way I use these and the way how I should... I don't know.

Anyway, thanks for the info.
