To keep your favourable assets, don't throw your pearls to the dogs, but seek very profitable exchanges instead. It's in the art of living. It means that one's own sincerity finds not too costy outlets somehow as well. So don't be sincere to your hurt. Often it is within your power to find a decent, fitting way to express your native sincerity and maintain good health thereby.
Art can be very helpful.
Artistic ways of expressing oneself can be fine too. Both great artfulness and skills can be trained. Zen has many good outlets. Haiku poetry is included. And many good points are found in folklore.
