Nothing in the world can bring me happiness. When something happens and I feel happy, it is only because I've gotten a glimpse of self beyond my own mind. Whatever seemingly caused my happiness isn't the true cause, because otherwise I could keep doing that thing to relentlessly increase or sustain my happiness. And of course this doesn't work.
The first scoop of ice cream is delicious, the fifth scoop gives me a stomach ache.
The first reunion with an old friend is joyful, by the 3rd day I need a break.
On and on. There's no exception.
I have to constantly remind myself of this because I keep getting entangled with the thinking: "if only _____ would happen I'll be happy"
