Don't ask me why, but humans feel indebted to others when they do something for us, right?
If you don't think: How do you feel when someone invites you to their birthday party or wedding?
Yes, in debt.
From an anthropological point of view, this makes us human beings more efficient, because the division of labor is possible.

They are relative to the principle of scarcity.
Or, to put it another way, wake up or you'll be left with nothing!

Experience is something tremendously valuable to us.
And speaking from experience is not the same as speaking from ignorance, or it should not be the same, but that is another debate.
The opinion of a professional or expert in a subject is key to successfully selling your proposal.
