I don't have cats in my head, but I do have "Pundravce u gaćama".
This is a little harder to translate, but it can be described as something that makes us restless, fidgety, and constantly doing something.
So I think that even after I have finished my working life, for which I am paid with that paper from the printing press, I will do something. Something I like, in the garden, in the yard, in and around the house. For myself, for my family, for my friends.

What I have done in my life is done and there is no going back.
There is no space for regret, I just learned from those actions what I want and what I don't want.

When I was younger, I used to say: "I may not know what I want, but I definitely know what I don't want". Until today, I have learned my lesson, so I know what I want.

Like you, to set a goal, to end mine paid career and retire to a quieter life.
