8th Grader aiming for Ivy League Colleges

I’m an 8th grader currently studying in British International School Riyadh, Saudi Arabia. I was recently introduced to the Ivy League colleges and I’m interested to get into one. I know that it is extremely difficult to get into an Ivy League college, nevertheless, I would like to try and aim for one. However, I don’t really know a lot about them yet and I wanted to know how I could manage my time and prepare for it. I have about 5 years left until I graduate from high school so it would be helpful if any alumni or any students currently attending an Ivy League College could give me some guidance. I think that I’m quite good in academics and I have an interest in music. I’ll be waiting for any advice.
