They say that much talk cannot be free from lies, and much wealth cannot be free from sins.
A good conversation requires the ability to talk a lot and exaggerate. Someone like me, who doesn't talk much, seems boring. Instead of beating around the bush and embellishing, I tell it as it is. Naturally, that seems boring. Those who talk a lot and speak well often resort to lying and exaggeration. However, as you said, practice in some areas is beneficial. You can become a good speaker without lying.
