All my Marketers that know what AARRR is - who & what did you study to master it?

I'm REALLY looking to do a deep dive into the subject matter! And when I say "deep dive", I mean spend over a month doing nothing but watching YouTube videos about it. Taking in all the patterns, nuances, and more.

Does anyone have any particular person in mind that is a GENIUS about the subject matter & deploying on it?

@LaniAssaf do you have any clue?! Also hi to both of you!
Hey squirrel!
No geniuses here, but I'm also intrigued by David McClure's approach, if you want to compare notes.
I watched his YouTube video going through this as well. You wanna link up and chat about this sometime?Maybe we can brainstorm some solutions for each of our situations.
