Marcus Aurelius said this quote

What need of prompt or hint when it is open to yourself to discern what needs to be done - and, if you can see your way, to follow it with kind but undeviating intent. If you cannot see the way, hold back and consult your best advisors. if some other factors obstruct this advice, proceed on your present resources, but with cautious deliberations, keeping always to what seems just. Justice is the best aim, as any failure is in fact a failure of justice.A man following reason in all things combines relaxation with initiative, spark with composure.
