Acievement has absolutely nothing to do with money - some people toil away their whole lives in offices, doing some stuff for a company, taking 5 weeks holiday, and making lots of money - they retire, the company disappears, everything they did is forgotten, they are forgotten - they did well for themselves, lived an OK life, but achieved very little.
My uncle worked his whole life for Vidor Batteries doing some managerial role, he company, the batteries, the factory, all gone, as alas is he.
Then you may have a painter or craftsman, who makes comparatively little, but his or her work is enjoyed and or used daily, it has utility or it brings light, it endures after they are long forgotten, that is achievement.
Raising the next generation well, that is also achievement, as is helping others.
Absolutely nothing wrong with the persuit of a good wage and a 9 til 5, but it should not be confused with achievement.
