Am I too late to pursue?

I'm 21 years old Korean.

I went to American high school and went to top70.? university for 2 years but with gap semesters, I actually attended 2 semesters total. I completely messed up first semester, tried to make up on the second semester but still my credit and GPA aint good. Eventually had to leave the school for personal circumstances.

I learned lots of things in these years that I couldn't see previously. I want to gather myself and move forward.

Now, I'm in Europe, taking undergraudate for 'business management and AI'. I'm graduating in next 3 years.

Here's my Plan A:

• 3 year of university

  • If I successfully follow my plan, will graduate with dual degree from another university in Europe.
  • Furthermore, during summer, I'm planning to do internships for Industrial AI firms in Korea. Even if its unpaid. I want to optimize my path as much as possible.
    • This firm is a industrial AI company that builds and deploys Ai solutions specialized for manufactoring and industrial and moreover military.

• As a Korea, I have to do mandatory military service. However, I'm planning to achieve bigdata and other certification (Industrial technician). This will allow me to substitute military service as an industrial technical officer.

  • Which I'm thinking to apply the same firm which I plan to do internship.

• After service, I want to pursue a full-time MBA back in US.

• Post-MBA, I'm aim for consulting or corporate strategy or executive roles.

I know that I'm already somewhat behind and that this plan might be far-fatched. However, I want to set a goal for myself to motivate and move forward.

I would really appreciate any advice or feedback on whether this plan makes sense and more importantly, on what I should focus on. To make this path effective and realistic.
