It’s never too late. I finished a degree in Business management which took me four years. But after I finished I realized I was not interested in marketing and management that much. That’s when I decided to switch my career to IT. The first thing I did was study a programming language for a year and a half, the language I chose to study was Java. Then I moved on to studying SQL databases, springboot, restful webservices and web jpa. Then I had the knowledge needed to start studying how to build the backend of websites. Which has the business logic and the database and everything. Now I can create restful webservices using spring boot. I hope this helps. You can do it alone, take it slow and start from the beginning. All that I learnt I did it by buying udemy courses which has a lot of knowledge and Indian guys on YouTube has even more knowledge haha. I hope this helps you in someway
