The truly trustworthy person often possesses two seemingly contradictory qualities: extreme honesty and extreme selectiveness.

They are honest because they are confident enough not to need testing or pretense to maintain relationships; they are selective because they love themselves enough not to let anyone casually drain their time, energy, and sincerity.
Honesty removes guessing from the relationship, while selectiveness establishes boundaries.
The more clearly a person understands themselves, the more they dare to express their true self, and the more capable they are of giving stable and reliable love.
