Ask yourself what kind of project you want to work on, and go from there.

You want to do web stuff? Learn Typescript + HTML + CSS

You want to do iOS apps? Swift

You want to do Android apps? Kotlin

You want to do AI stuff? Python

You want to do backend servers? Lots of options here, but Typescript, Python and Kotlin are well-supported on the backend too, so I'd go for one of those.

You want to do database work? SQL + whatever database you're interested in. If you don't know, go with Postgres.

You want to do games? Ask someone else, because I don't know lol
