“An insincere and evil friend is more to be feared than a wild beast; a wild beast may wound your body, but an evil friend will wound your mind.”
Sincerity is crucial to a long-lasting friendship. Sincerity means being honest, truthful, and meaning what you say. Without sincerity, you will never be trusted by your friends, and without trust, you can never establish a truly meaningful friendship. Always be up front with your friends, and always be yourself. Don’t hide things from them, and you will be able to work through any conflicts you may encounter because you trust each other.
