Maybe for some people, they see work as just a way in order to earn money for a living, but to some people, they see work as their passion and I don't see any problems with that. Yes, having vacation and resting is really good, and most people will like that, but being always in a vacation and not having any work just because you are earning money from an investments (if you are earning good ROI) could be really boring. Yes, you'll enjoy it at first, but you'll always seek for something to do.
Also, remember that investing does not give guaranteed profit, knowledge and capital is also needed in this. If you doesn't have this things, earning could be really difficult.
You got to enjoy vacation during Christmas or lunar new year, but you would still feel empty in life. I think vacation isn’t really what you’re after, what you’re after is enjoy what little time you have living on this earth, vacation is just part of the deal not the final product and that’s why you feel empty because you didn’t receive the product but a empty parcel from your express delivery, can you ask for a refund?
