To be clear I am not being sarcastic in saying this but the only method I’ve found to work with any consistency is: Try, try again.

I find this is what works for me. I seem to be quite a nonlinear learner. I struggle with the methodical x leads to y leads to z approach.

I tend to try and take on the whole thing and not really understand it then repeat the process (often from different sources) after a while I just seem to understand more and more
