You're feeling like a "Virtuoso" between fiat slave and retired

But seriously, I think the phrase that comes closest is "Virtus", which means "virtue" or "manly excellence". It's Latin for someone who has cultivated their skills and character to the point where they can live life on their own terms.

However, if you want a more relatable term, you might say you're in a state of "Eudaimonia". It's an ancient Greek concept that roughly translates to "happiness" or "flourishing", but it's really about living a life of purpose and fulfillment.

So, yes, you're definitely not just pottering around – you're living your best life, virtus-style!
