I got your point. But 100% selflessness is hard to achieve. Sometimes you may need HBD or sometimes you may need attention for your post. Like 5% to 10% ego and 90 to 95% selflessness would be more flexible. If we can make 100% selflessness that would be better.
But a question is should we stick at 100% selflessness.
By the way I did not upvote myself since the time I can not remember.
