Seriously, ChatGPT was the thing that gave me a foothold into the AI/machine learning world... because it gave me hope that a mere mortal can achieve something reasonable with this tech without a crazy amount of work and educational background.
There are really great resources now from eli5 about all of this tech to books like ‘the little learner’ which any programmer can get into. Yes, it takes effort but it is a great time for it.
Regardless of what you want to learn, "small daily activities" is a bit hard. You can learn some stuff by osmosis, following the feeds of AI devs && AI channels, but the bulk of what I learn comes from starting projects & digging into code & reading papers.
If you can hold attention span over several days (I can't), work on a project bit-by-bit. Just make sure it uses modern AI stuff, and that you have smart people to talk around with.
