Long trips on planes/trains/busses would be a lot more enjoyable.

I used to be a picky eater, but years ago I decided that I wanted to like more food - - that life would be better if I actually enjoyed foods that I would otherwise have to suffer/avoid.
I started by putting small amounts of different ingredients in my dishes (when it made sense) and I quickly developed a taste for all of them.
(Only found out later that this was a great way to do it as your microbiom directly impacts your cravings).
Onions, mushrooms, tomatoes, olives, pickles, brussel sprouts, oysters, mustard are all things I now genuinely enjoy.
