I think that in life you need physical labor, mental labor and such labor where you need to use the strength of the spirit and your character. Development can be obtained anywhere, you just need a different experience - situations in which you cannot survive without mind, without character, etc. Money is just a temporary measure of the value of things/services, but your personal skills that you have acquired through your work are for life. With the help of such skills, you can make money in any situation and have everything else. But you always need to listen to your intuition (what your heart tells you), even if it seems illogical.
