William Walker Atkinson 
Memory How to Develop, Train, and Use It [EPUB ebook] 

This book seems to be the most likely way to remember things well – and it explains the science behind why. When you give full attention to something, it raises an interest in your mind. Then once you’ve paid attention and kept a sustained interest in something, you need to associate it with something. That is how the mind recalls. If you are interested in putting in some consistent work, I believe this book would be a great place to start! (Goodreads)
