What recommendations would be useful for a 9th we grader interested in the Technology field?

I’m a 9th grader with hopes to make the most of my 4 years. I am aware of stress and am asking for wise advice and what should I look for based on my interests. I have a goal of getting accepted into MIT one day, but I don’t want it to be something the weighs me down when I hear my stats aren’t good. I obviously have other options for colleges but that’s at the top of my list. What are smart ways that can help make my history better without overwhelming myself? I’m interested in working in Computer Engineering, Cybersecurity, business, and leadership one day. What online programs do you guys suggest to start my skills and development journey? I plan to take a coding class and I’m currently in robotics. What do you all have to add? Thank you!
