People of course will always raise their living standards after they reach new goals. Since humans long for limitless/boundless expansion. But the work will always be the most gangster thing you can do in life. But a person usually forgets how good work made them feel and one day they wake up everyday asking how they can please and stimulate themselves as the new form of happiness.

But work and engagement will always be what will give the best feeling in the long run. There is a good book about that called flow. But humans forget very quick how fun the work is when you are pushing into your edge. It can be a challenge to find that edge. But that is what makes life fun. It's suppose to be hard. The hard is what makes it great.
