Great human beings live for others, knowing that it will not yield benefits to them. Yet they do it. They know doing that has personal costs and willingly pay them. Thats why they are called “great”.
It is only bcoz of the greatness of some people that you get to enjoy freedom today. Had freedom fighters used your approach to life, we would have been in hell
You had misunderstanding that living for others yields benefits! You happily live for yourself. Good for you!
