However, my lifestyle is not much different than yours, and I get what you're talking about. Keep in mind that not everyone with the potential can actually find his best way :).
One more thing. For your friend, money means safety. For you, the validation of your own value ;). Basically, you are looking for different things in life :).

As long as they are honest with their choices, they can do whatever they want with their lives.
