When the strong encounter sincerity, their first reaction is to cherish it; when the weak encounter sincerity, their first reaction is to try to control and manipulate it. Sincerity is never a cheap act of weakness; it is the very best kind of composure, the most scarce resource in the soul. Remember: your sincerity is precious—never waste it carelessly on people who don’t deserve it. Only true strong ones deserve this limited-time gift.
