I've noticed that as I've gotten older that I often forget things, i.e., where I put my keys, or I walk into a room and for a second I can't remember why I went there. Sometimes, to make sure I don't forget something that I need to take with me the next morning, I write it on a post-it and put it on the front door. (This has  been very effective! I no longer have to turn around and drive back home.) However, I have been hearing about methods of improving your memory and I came across these suggestions. They are actually quite good. Check them out.
