Ask HN: How to self-learn ML/AI?

since this could have various responses depending on different backgrounds I'll give my particular case but feel free to share advanced resources, it may help others. I studied economics for a while, have very little experience with a few programming languages and prefer learning by doing, so in a perfect world I'd rather start with the resources/tools that will let me start building small things asap and go from there. thanks and have a good weekend!
