Things we like

What is your view on our individual tastes, likes, and dislikes?
It seems they are just thoughts, so does it mean they can all be changed?

For instance, I don’t like to hang out in bars. After a drink or two, I get extraordinarily bored, I don’t enjoy talking to people who are drunk, and I much prefer being in bed with a book.

This is all purely based on my thinking, right? So if, for some reason, I wanted to enjoy going out to bars more, I could retrain my brain to like it?

I feel like our likes and dislikes are part of what defines our identity and personality. So if I can just change them however I choose to, what would you say is the seat of my personality?

Thank you!
