I've observed that by putting great effort into learning concepts which initially seem incomprehensible or very difficult to conceptualise, even if it may at first appear like I made little or no progress, I usually end up with enhanced cognitive abilities which extend beyond the concepts I was training myself to comprehend. For example I'm a chemistry student and although my thinking style (which is a combo of visual and kinaesthetic) gives me an edge in some areas of chemistry, it seems to make others areas a huge challenge, to overcome which I have to spend a long time contemplating the concepts from different angles until I eventually gain an intuitive understanding of them. I've noticed on numerous occasions that as a result of my arduous efforts to gain this intuitive understanding, I not only gain the intuition necessary to contemplate these particular chemistry concepts, I find myself with the ability to think about things that I was previously incapable of contemplating dexterously. These cognitive abilities only become available to me days later. I suspect neuroplasticity may play a role in all this. I think that I end up with these additional cognitive abilities days later because my brain has literally formed the connections necessary to think in such a way. I'm guessing plenty of you here have observed this kinda thing too.
