Trust (glossary entry)
A sense of trust in another person is usually built up through a history of observing that person's behavior and comparing to one's own core values.
Trust in oneself is built much the same way (by observing one's own behavior).
As this comic illustrates, "commitment" can be driven by ego or reinforced by ignorance, and this often gets in the way of one's success.
As this comic illustrates, overconfidence often results from inadequate awareness or a failure to think about the situation, and prudence is often blinded by ego.
A More Robust Basis for Trust
After being "fooled" by false confidence, foolish commitment, and other similar behaviors, one usually learns to apply more robust standards, incorporating qualities from all of the mature archetypes.
The word "trust" is often used to refer to an abstract or philosophical type of "love", as in this example:
These men have my unconditional love, trust, acceptance and respect, because even though I do not know how they will behave, I give them the opportnity to do the best they can and then offer any support or help that I can offer and which they will accept.
There is more on this in MCV07, Be Unconditional.
