Answer 1

It's difficult to give good advice without knowing your interests, circumstances and current level of knowledge.
Generally, learning about web technologies is useful for a beginner (HTML, CSS and Javascript). Also if you get to intermediate level with these, you can create quite spectacular web pages, which is not really true for most other languages here that only use the console.

If you are interested in application development then it would also be worth to study an object oriented compiled language, such as Java, Kotlin, C# or C++.

Try to focus on one thing at a time. We get easily distracted because there is just too much to learn that is impossible to cover in a lifetime. So we need to pick wisely :)
