What should I focus on now if I want to become a police officer at 21?

Hello! I’m currently starting 8th grade and planning my long-term path toward becoming a police officer with the Colorado Springs Police Department at age 21, if I meet all requirements.

Current situation:

• A+ Grades
• Interested in robotics, coding, writing, and public speaking
• Active lifestyle
• Already saving money
• Considering IT work as my main career before law enforcement

General plan:

• Finish high school with strong grades
• Work part-time during high school
• Earn IT certifications instead of a 4-year degree
• Work in IT from 18–21 to gain experience and save money
• Apply to police academy at 21 if eligible

I have a couple questions:

1. Is working in IT before law enforcement actually useful, or would a different path make more sense?
2. Are IT certifications enough, or should I consider a degree anyway?
3. What skills or experiences would make me a stronger police applicant later?
4. Is there anything I’m overlooking in this plan?

Any advice is appreciated.
