Is it worth investing one's time in things which cannot earn the person money? Things like helping someone with a direction to a place, asking someone whether he or she is doing well, dating, e.t.c?
Of course, it is! It is called kindness. There are things that shouldn't be paid for we do it out of kindness. It's not always about the money, someone's smile or simple thank you is enough and I believe that's how we become more human.
