What metaphors are used in Cold Fire by Dean Koontz?

Example of Metaphor (and simile):

"Life... it's like gettin' a blueberry muffin in a coffee shop when what you ordered was the apricot-nut. There aren't any apricots or nuts in it, and you can get tied up in knots just thinkin' about what you're missin', when the smarter thing to do is realize that blueberries have a nice taste too"
