I've been trying to use the phrase "I'm not in the right headspace to hear a new song" or "I don't think I'm ready to watch/play that" more actively.
Minds are very very conditional, and whether or not I like the cool new thing you wanna show me is as dependent on my mood and state of being as the quality of the thing itself. If I want to give something a fair shot that my friends love, I find that approaching it when I feel ready is super important.
