Dear son, this is an important concept in many ways. I have seen people working hard to buy a new car or house or similar when they were actually looking for happiness or fulfilment. Some one sold them material things and only after a long walk they realised that they were on the long road.
Some people will tell you that one political system is better than other. Any which delivers Justice is good enough.
I let you look and think where ever this concept is applicable in different stages of your life.
