Seeking Advice: How Do I Start Learning Coding & Switch to an IT Career (Without Going Back to School)?

Hi everyone. I’m hoping to get some guidance from people in the IT industry.

I’m currently working full-time as an office manager (night shift) processing loans with about 4 years of work experience. I didn’t graduate college and I can’t afford to go back to school, but I’ve always wanted to get into IT. I grew up around computers and I genuinely enjoy tech — and I also know that IT offers great career growth and income, which is a big factor for me as well.

The problem is… I don’t know where or how to start learning. I really want to shift careers, but with no degree and full-time work, I feel lost.

My goal: Within the next 2–4 years, I want to be able to land a job in IT thats within 6 digits. I know this won’t be easy, but I’m willing to put in the hours.

My questions for those in the field:

1. Which path or skills should I focus on if I want to reach 6 digits? (e.g., Software dev? Cloud? Cybersecurity? Data?)

2. Where can someone like me start learning for free or cheap? Any recommended YouTube channels, free courses, beginner-friendly roadmaps, or certifications?

3. Is it realistic to enter IT and reach that salary level in 2–3 years without a degree, assuming I work hard and study consistently?

4. What would you do if you were in my shoes?

I’d really appreciate any advice, personal experience, resources, or even reality checks. Thanks in advance to anyone willing to help — this is something I truly want to do, both for my future and because IT is something I’ve always felt passionate about. 🙏
