Waste no more time arguing what a good man should be. Be one. – Marcus Aurelius
Arguing is generally a waste of time (but only 99% of the time) (better to have an actual conversation, where real listening takes place and ideas get exchanged and considered).
There’s no point in debating what it is to be a good man; just pick something that will improve your character – your way-of-being – and do it.
Waste no more time: act.
