I like this positive quote by Norton Juster. Possibility/Probability theory is a mathematical concept that Zadeh (1978) put forth as a possibility/probability consistency theory. I consider it more as an optimistic outlook. The Oxford dictionary defines it as a thing that may happen or be the case.

If you have possibilities, you are optimistic about the future. When my ex-partner died of Alzheimer’s Disease in his sixties, I felt pessimistic. My possibilities seemed limited. Then I wrote a book of poems about the experiences. This was recently published in a collection called, “Touch My Head Softly,” by Finishing Line Press. I opened up many possibilities for me, as well as giving me closure on much of my grieving.
