Sadly, in surrendering our effort in these activities, we gain relaxation, but we may actually give up a lot of deep enjoyment because, in fact, it’s often effort that ultimately creates long-term satisfaction. Of course, it might be that others can do better wiring work or gardening (in my case, this is certainly true), but you might ask yourself, “How much more will I enjoy my new television/stereo setup/garden/meal after I work on it?” If you suspect you would enjoy it more, maybe those are cases where investing more effort will pay off.
The author doesn’t take into account that there is enjoyment if you pay others to do things for you because your effort was in making the money that enabled you to do so.
