At some point, the work becomes the hobby. If you had fyou money, what would you do? Presumably not sit and stare at a wall all day. You'd do something you enjoy I assume. And for some, running one of the world's most powerful entities is enjoyable.

I could definitely keep myself entertained. Maybe that's why I don't have f-you money.

If your job involves hearing smart people talking to you about amazing ventures before getting into a fancy restaurant the night before you take a plane to some foreign headquarters it earned the right to be called a hobby.

I'd just learn.

Learn everything.

I have a goal, it is to be better than average at every "skill".

and then what?

lol, you know its not possible to learn everything! There is no "then what?". Then entropy catches up with us all and we die eating at The Restaurant At The End Of The Universe.

Because in most cases, your needs rise together with your salary. Once you start earning 200-500k/year, you just get a house/car/boat that costs nearly that much to maintain. Obviously there are people who keep their cost of living low and stash that money in a saving account so that after 10 years they can realistically stop working altogether, but that's not the pattern that I'm usually seeing.

Consider the possibility that what you may perceive as work, someone else considers play with certain benefits.

If you have certain goals in life e.g. building certain large infrastructures, it might be beneficial to do these in an existing company than starting your own or doing it in a nonprofessional environment.

Plus, yes, there are other goals than "not working".
