Not exactly giving a direct answer but just wanted to talk about the mindset.

I think it’s different for everyone. Some people need time to before feeling comfortable to build up a close relationship. Some people can click with people quickly.

Even a more reserved person might be able to click with another person quickly given the right chemistry. Other times it might take a while.

I’ve also seen social butterflies who can be friends with most people but have trouble making deeper connections.

There’s definitely no “best way” to be friends / best friends with someone. Usually it just happens after spending some time with together and the both of you enjoy each other’s company.

I’d Just say to keep an open minded about it. People can be different and that’s fine. Touch grass now and then, join some hobby classes (consistency helps), do some volunteering.
