Half empty or half full?
Why are you obsessing about the fulness of a glass?
Stick the same water in a smaller glass and it’s full.
Put it in a larger glass and it’s nearly empty.
This is not about the glass; it’s about the water.
A fish never asks if the glass is half full or half empty, only if there is enough water in which to live happily.
Stop obsessing about your glass, check your water level.
