This Too Shall Pass

Take a look and see if this is cheering. The lyrics send a timeless message: This too shall pass.
Whether joyful or painful, the moment is fleeting.

Why then does the painful seem to last so much longer? Our brains give negative information twice as much attention as pleasant input. Why then would we be made that way? I think the answer is easy to guess. Pleasure and pleasant things are unlikely to harm us while things that cause pain just might!
Knowing that should help us to be a bit more patient in the darker times and anticipate the dawn as this song suggests.
