Optimism + Pessimism = [Realism] Shades of Gray

Is your glass half full, or half empty? If I’m drinking from my glass, it is half empty. Or empty. At which point I’ll want more or I’ll be satisfied. Empty is acceptable. IF I’m preparing my beverage… My glass is half full. In that time I recognize that I only want half, full, or anywhere in between. Half full is acceptable.

In a world of black and white,
Does anyone else see these many shades of gray?

Where do you see them?
How do you deal with them?
