I had the same opinion as you for some time, but I'm reconsidering that stance since I went back to university in my 40s. To say I have a very bad working memory is an understatement. I'm distracted by just about anything (like now by the noisy neighborhood) and it has been like this "forever". Still, I was able to graduate with honors and outperform the students with an impressive working memory, even in projects involving creativity.
