Studying abroad?

I am 13 years old, currently in 8th grade in Bangladesh, and I have a clear 8-year mission to become an AI Developer in Germany by 2033 and settle there with my family.

I am reaching out now because I believe in starting the 'grind' early. I am obsessed with Math, Science, and English, and I have already achieved a typing speed of 87 WPM with 97% accuracy. I am currently mastering Python (using Mimo).

My Roadmap:

Academic: Maintain a GPA 5.00 through SSC and HSC (Science Group).

Language: Reach German B2 by the end of college to unlock free tuition in German Public Universities.

Technical: Transition from Python basics to Machine Learning to become a specialist who can both build and 'fix' complex AI systems.

Goal: Secure an EU Blue Card in Germany to provide a 'Heavenly' life for my parents and myself.

My Question to Seniors:

For those already in Germany or working in AI: What is the one thing you wish you had started doing in Class 8 to make your journey smoother? Also, should I focus on the Studienkolleg (T-Kurs) path or Ausbildung or try to find a direct-entry Bachelor’s program in AI once I finish HSC or any other Education
