"I wouldn't want to be obligated to anyone because they sacrificed their own happiness for mine."
What a desolate and barren world where we fear connecting with others in case we might incur some sort of obligation.
Because people don't live according to his message right now, we make ourselves miserable by trying to repay the debts of other people's sacrifices for us. Rather, I would have it so we pay those debts forward to the next generation by enabling them to do what makes them happy, not holding them to some standard of what we think makes people happy just because we raised them or provided them with the means or money to do something they enjoyed.
