> Just realized that that is how I think... :facepalm:
When I see someone spending too much money on unnecessary things (unnecessary according to my current view) I think: "If I get rich I should donate a lot of my money to people in need." But along with, I do also think: "Did this guy too would/did think the same if [s]he is in short of money?" or "Will I change my mind if I get too much money?"
We can do dream or think of our actions in many hypothetical situations. But we can't ever be sure what we would actually do if such a situation happen.
