Feeling pissed (“angry, fed up”–per the Online Etymological Dictionary) is an opportunity to do P.I.S.T.: Pollyanna-Ish Self-Talk.
I repeat: Feeling pissed? Do P.I.S.T.
‘How does one do P.I.S.T?’ you ask yourself. You do it by asking yourself, ‘What can I be glad about in this situation?’ That is Pollyanna’s “Glad Game.”  (Never heard of it? It’s in the book that bears her name! A great read!)
Remember that life teaches us many things. Find those things–make it a game! I’m hoping to remember this form of Cognitive Behavioral Therapy, myself. It’s kind of . . . catchy. 😉
Go ahead and get pissed, but then do PIST!
[Note: These terms just occurred to me as I was replying to my niece’s Facebook post warning against mixing soda pop and laptop use. My personal muse must be working overtime! Ha ha! :-)]
