The concept of Enough

I used to think that enough was a word that described physical objects, as in, "George didn't have enough money for lunch," or "Phyllis has enough carrots to share with George." It was until I read a Hillerman novel that I realized the concept of 'enough' could be used as a philosophical standing. "Enough" vs. "never full." Given everything I've been through in the past 4 years, you'd think that concept would be blindingly obvious to me. But as with many things...fear keeps me from looking too closely. Fear...closing down...never enough. Knowing fear generally means an acceptance of fearful states. Keeping from shutting down is the trick to it.
