Quantum entanglement of pessimism and optimism
It would seem that in order to be negative over time on a certain topic one must maintain some belief that it ought to be better.
A person who complains often about their work must implicitly imagine and desire a preferable job.
Anyone who wakes up each day with negative thoughts about their home must have some vision for another place to live.
Someone who persistently dislikes their state of affairs would certainly prefer another way of being.
Negativity may be tied to a desire as much it is to a disappointment.
What is bothering you today and where is your hidden dream for something better?
