Until I was 30-something I thought I just didn't like coffee or chocolate.
Then one day I had actually proper coffee, and I discovered that good coffee isn't just some imperceptably theoretically better version of regular coffee that snobs are basically just faking being sophisticated for show. They are two entirely different things.
Same even more so for chocolate. 99% of chocolate products you come into contact with are garbage. Actual chocolate is like an entirely different product. It's not a better version of the usual thing. I ate it and thought "Oh. Ok THIS must be why chocolate ever became this huge thing in the first place. Hundreds of years ago before all the industrial process and market forces produced all the "chocolate" I ever tasted in my life, what they had was this, actual chocolate. Of course they loved it."
To restate the point, I was never happy with the regular version in the first place. I assumed "I don't like coffee" or chocolate, the same way I don't like cigarettes. Turns out I love them both.
And it's possible to continue to enjoy the results of having discovered and grown some taste in some area indefinitely without diminishing returns or anything like that. I'm not much of a sweets person so I still don't buy a lot of chocolate or chocolate things like cookies etc, but we have a Trade subscription and get a new and different bag from some random indipendant roaster every 2 or 3 weeks and it's great. I don't love every single bag but I at least find them all interesting and I do love the overall high level of quality basically all the time. I'm not now overall poorer for having discovered good coffee. Life is better. And what else is there?
