You never get what you wanted to get or you get what you wanted but didn’t realize that was what you wanted or you get what you wanted and realized you wanted but didn’t think that it would be what it is when you actually got it. Or you get what you wanted at a time and place you didn’t want it. Or you get what you wanted along with what you didn’t want and wish getting what you wanted didn’t entail getting what you didn’t want. Ultimately getting what you wanted sometimes makes you want to never have wanted it in the first place.
Maybe never getting what you wanted is better than that. Marginally.
