Sleep helps memory too. The better rest you get, the better your mental and muscle memory work.
So remember to rest during the day and the night and it will do your memory good.
I was happy to pick up this recommended book, The Secret Life of Bees by Sue Monk Kidd, and find it to be quite delightful. It's a story of a 14 year old girl who leaves her home to find a better place. While there, she is able to learn and grow while letting go of the guilt she's felt over many years.
