Any advice to start early on a career in IT?

I’m still in High School ready to begin a career path in IT. What can I do to
advance this? Are there certifications I can and should obtain? Certain skills
I should pick up?
Basics
I have basic Java, C++, HTML skills (Based on the classes I have taken in school) but I am learning these languages in depth one by one. I really enjoy programming, and maybe a course towards entrepreneurship.
