These thoughts come in response to how you’re feeling in the moment. They are thought blocks.
A block of thought about the cake, then back to work, then a block of thought about dinner, and your thoughts return to what you were doing, a block of thought about how you look in the mirror, then forward thinking to the next thing in your day - feed the cat, pay the bill, the deadline at work...
Whatever you think about comes in short, intense blocks, …bam, bam, bam!!, & you respond to the thought in the moment - eat the cake… set a mental need that pasta is the only dinner solution tonight; and feel negative about yourself all day!
