I would absolutely recommend the Roman Stoics. The privileged ones lived like kings, but were prone to lose everything if the political climate changed. Their lives were absolutely unpredictable and they found ways of dealing with it in their heads. One can read advice from a philosopher/teacher who was later killed by his disciple (Seneca, forced to commit suicide by Nero), maybe the best Roman emperor ever (Marcus Aurelius) or a slave who was freed only later in life (Epicetus). Those guys knew that nothing was theirs forever but dealt with it in a graceful way.
