Class 1 : people whose hobbies mainly involve spending money ( examples : eating out, travelling, collecting infrequently used items, soliciting services with no durable consequence, drug consumption ) ; subclasses ... has too much money \ has just enough money \ has not enough money.
Class 2 : people whose hobbies mainly involve designing and constructing ( examples : engineering, commerce, art, politics, activism, craft, academia, athletics, research, development ) ; subclasses ... has too much money \ has just enough money \ has not enough money.\
I need to start massaging Class 1 folks out of my schedule, and acquire more Class 2s over time. I did think about this a bit last year, but I didn't act firmly on it, as I spent many hours helping friends. Maybe I need to be less helpful.

Addendum, as some readers are not getting the point :
Some people think that enjoyment is the point of life. Enjoyment is a device in individuals, which carries the function of getting individuals to do what civilisation needs them to do to get civilisation to where will end up. When civilisation reaches the end, the device will not have its uses, and so enjoyment has no place in the long-term view. Some people like to live in the present, wonderful. Some people like to focus on the future - also wonderful. But that probably means these types will not get along in the present, so much.
