How to be the OG engineer

My goal, for the foreseeable future, is to become the OG engineer, to be able to build anything in a weekend that my brain ideates

What's the most efficient way to learn new stuff? I wanna start implementing all these project ideas I get, but all these ideas are of such diverse tech domains. I wanna learn GenAI, IOT, blockchain, ML and also how to make drones, but things keep pooping up and finally jab thoda sa time milta hai toh college exams hit. So what's the trick to learn new cool interesting shit as fast as possible. Mastering all these domains won't be possible I know, I just wanna get enough knowledge to be able to make stuff
