Some people don't like trying new things because they're afraid of failing or doing something wrong. They think about all the ways it could not work out, which makes them nervous. And if it's something really different, they might be scared of being rejected or judged by others. They don't want to make mistakes or stand out in a bad way.

I think the reluctance to try new things is because of fear. We usually live our lives the way we want and follow a routine. When something unexpected happens, it can make people feel stressed because it disrupts their routine. Not everyone is like this, but some people find it hard to deal with changes. They find new things challenging, so they avoid them. I don't really understand people who are like that, but I guess everyone is different.

Some people just aren't interested in trying new things. Maybe they don't see how it would be good for them, or they might think, "What's the point?" They're happy with their life as it is and don't really want to change anything. They like their routine and don't see a reason to do something different. It's not that they don't like new things, but they're just not looking for them.
