G'day

I am learning this piece  at the moment, To help me to memorize this piece and I also need to write something about this piece. I find that  the left hand is harder to memorize because there is various form to remember and I find that bit confused sometimes. The middle part, how to play without too boring, can anyone advise me about speed where should I increase or decrease?  Some people said to play it more romantic  more dreamy. However, I feel I play it like a  dead warm up. Can anyone advise me? Can anyone give me the background and period about this piece. Why, how and what Chopin wrote this piece. This is the first Nocturne, is there any special from other Nocturne, theme?  Is there any history and story about this song prompted Chopin to compose this piece. Anything I would appreciate very much !!
