Just as the nature of rational things has given to each person their rational powers, so it also gives us this power -- just as nature turns to its own purpose any obstacle or any opposition, sets its place in the destined order, and co-opts it, so every rational person can convert any obstacle into the raw material for their own purpose.
-- Marcus Aurelius, Meditations, 8.35
What things do you think have been holding you back that, in fact, can be a hidden source of strength?
