I personally found that I would have to keep exposing my brain to the same mathematical concept many times over days or weeks by doing problems when I could and visualizing the math in my brain when I was doing other things. Over time it felt like my brain was gradually getting "imprinted" with the shape of the math ideas, but you had to be gentle and do it over a period of days to weeks, otherwise it's like the math shape would just squish your brain instead of letting your brain adapt to it :)
