That is what is like with all life situations. They are mystery until they happen to you. You don't know what cancer is like or the death of a loved one is like until those things happen to you, and you don't know what the boredom of abundance is like until you have it either.
On the latter, the important thing to get is that much more of what motivates us survival driven than most people realize. When survival is sort of guaranteed, a lot of motivation can dry up along with a lot of the juice of life.
