I said that because the parent comment said "I just don't understand this at all. If you can earn a million a year, do it for 3-5 years, never have to work again, and pursue your passions in life." They don't have those passions in life per say and fill that void with work and other things. You are actually echoing what I'm saying in your own way.
Also, I like how people bring up gardening sometimes when passion is discussed. To me, passion is coupled with expression and allows you to take on an identity in some other "world". You can be passionate about music, you can have your musical identity. You can be passionate about mathematics, you can have your way of reasoning about problems. But gardening? Is there a difference between things you really like to do and a passion?
