Nobody dies of no contentment. To live is to do duty towards ourselves and live by principles. Death can be out of RTA or disease or murder. Keep only your yardstick in life, but that's impossible if you interact in a world full of notoriousness. Be selfish to become selfless. Truly I like what you wrote. Look for your goals and ambitions not what the other human being is contemplating against you. Marcus Aurelius has written a sensational stoicism but the world discovered it many years after he died. So nothing goes waste if you give all your might to it. Otherwise you wouldn't be writing. Grace to you. Thanks.
