You bet, in the media, what bleeds, leads. No surprise, public speakers hesitate to focus too much on the positive. They fear they will be ignored as "out-of-touch."
Yet, hammers Amit Sood of the Mayo Clinic, the messages about kindness and even joy, if positioned right, can trump all else in connecting with our fellow human beings. That's because we humans hunger to figure out the meaning in suffering. Do that, usually with the help of your fellow human beings, and the pain lessens. Maybe even goes away. You can read that shocking reality in "The Mayo Clinic Guide To Stress-Free Living." Even though Sood's book had been published way back in 2013, it remains in the 5,000 ranking on Amazon.com.
There are myriad ways to equip the audience to take deep dives into meaning.
The most simple is a visualization exercise. Ask them to paint a mental picture, with lots of color, of a stress-free moment. Then you speakers can share your own picture. Explain why there is no stress. It could be a snapshot of yourself listening, actually being fully present, to your four-year-old child.
A more complex way is to have the audience meditate for three minutes. The mantra would be, take a breath in, say "Clear Thinking," and let that out, saying "Don't know." Since we really don't know, do we, what's ahead, it's a waste of time to be preoccupied with threat.
