Thanks for the kind words! Certification courses are generally a good way to introduce you to a field. Because they are online and don't cost that much, I would consider it low-risk; meaning, if you decide you don't like it at all, you can simply just stop.
It sounds like you're on the right path given your past interests. My biggest tip for you is to remain curious and ask lots of questions. Remember to focus on the core problems of people and don't just jump into solutions. Best of luck!
