the connection between optimism and resilience in the atlantic:

“Resilient people are good at bouncing back because they are emotionally complex. In each of Fredrickson’s studies, resilient people experience the same level of frustration and anxiety as the less resilient participants. Their physiological and emotional spikes were equally high. This is important. It reveals that resilient people are not Pollyannas, deluding themselves with positivity. They just let go of the negativity, worry less, and shift their attention to the positive more quickly.”
