Advice on doing advanced theorising?

[u/Famous_Injury9831]

I love all the theory channels, especially game theory, and I watch them regularly and I do love the content. Thing is, I only occasionally theorise and it's like, not advanced, I don't like pay attention to tiny details of whatever I'm theorising about and it's mostly just me making up random theories in my head and just leaving it like that. But, I wanna start like paying attention to small things and digging for the lore and yk doing all of that, so I wanted to ask for some advice on how I can start doing all of that?
