The trite response is "get better at maths". I honestly don't mean that facetiously - the whole understanding that underpins "neat tricks" and how to use them is "maths". Once you can use said neat tricks, you are better at maths. So, I would suggest a better question is: where can I find an introduction to this stuff that is better aligned with my current understanding and knowledge. To that end, here's a great intro book: https://www.dspguide.com/ https://www.dspguide.com/ I read that cover to cover when I was 17 and I would not have been described as particularly mathematically gifted.
