What may you recommend for learning MoI? (basic and advanced stuff)

I know basic things but I would like to learn thinking in MoI style and of course how to fix errors alone (for example blend and fillets).

I`ve asked many questions here and every aswer amazed me becouse I would never solve it out alone.

I`m mainly polygon modeler (Modo) and I think in way: create shape /do falloff/workplane work/extend edges/linear align vertices/move edges along other other edges/do bridge/close gaps.

I can`t understand MoI way deeply. May you give me some advice what is worth to watch/read to understand working in MoI deeply? (I`m interested in paid and non-paid stuff)

I think I am missing some basic knowledge.

Thanks in advance.
