Yes, @soldier. I searched a lot about programming last year when I also decided to change my field, just like you. I was an accountant and holds a master degree in business. Very happy to see that people like you who work hard get success. I, unfortunately, haven't succeeded in my life yet.
Wrote a blog about my life, you can read it whenever you get free.

P.S Not sharing this article for your upvote but just wanted to share the story of my hard work and still going on.
Thanks.
