Today I will surround myself with happy thoughts and feelings.

Thoughts arrive uninvited all day and there is no doorman. What you have a say in is which ones get offered a chair.

An unpleasant one can pass through in four seconds. The same thought, rehearsed, becomes a twenty-minute feature with a full cast, and by the end you are annoyed with someone who has not done anything since Thursday. Surrounding yourself is less about summoning good thoughts than about declining to grant the bad ones a lease.

When you catch yourself in the twelfth rerun of something today, that is the moment. Not the arrival — the rerun.
