Trust is a curious thing. It is often given freely with a 'sure, why not?' or 'of course!' This is the best kind of trust, I think, because you tend to fully open your soul (being, heart, mind, faith, whatever) to someone/something ... which just makes it so much easier for other people to get closer and understand you. Or take advantage. Blind trust can be a conversation-starter, or it can be a disaster. "Will that rotted rooftop support me as I walk upon it?" "Will my car make that 400 mile road-trip?" "Will this person treat me the way in which I deserve?" It's a leap of faith. A roll of the dice.
The other method of trust is the one which is earned. While more logical and based upon thoughts and actions, I think this is the more difficult one to attain. To earn trust from people, doesn't that mean that you are starting off on unequal footing? And at what point does it become truly 'earned'? Does that not mean that there are goals and levels set by the trustee? What happens when those levels are either too easy or too difficult too attain?
And there's a third type of trust. It's not so much a median level between these other two, but a combination where experience, intelligence, and insight make the trust goal both easily attained and already earned. While I agreed to this being 'trust', I have another word for it: Knowledge.
