This part of your speech, the warning as opposed to the rousing, needs to be amplified and I will probably write an essay about it very soon. The difference between resonance and discerment needs to be amplified. The notion of following one's heart needs to be cautioned as too many believe they are following their heart when they are actually following their emotions and no one should make LONG TERM decisions based on emotions. Love, which can be both a state of being, a true feeling and an emotion greatly confuses things.
I cannot adequately cover this in a comment but YES, people must learn how to practice discernment vs resonance.
