Value of a paisa

I remember my dad telling us that we did not know the value of money. He used to say that if we earned a paisa (penny) we would know how much effort it takes or how hard it is.
At the time I used to get upset, but now I realize how hard it is to earn a decent living, and how difficult it was for him, to put in gruelling work hours and raise four young children. I miss him so much.
