Yotsuba!-Volumes 1-3
I've owned the first 3 volumes of this for a little while but I've only just gotten around to reading it and wow, do I regret leaving it so long. I. Love. This. Manga. It's like the ultimate feelgood experience. I just spend the entire time with this giant grin on my face. Seeing the Yotsuba, a young girl who has moved to the city for the first time with her Dad, explore and learn about the world is incredibly cute and endearing, and her mischievous antics and boundless enthusiasm often left me in stitches. The art style is fairly simple but at the same time very distinct, especially the facial expressions of Yotsuba herself. I'm not sure if it's because it pinpoints things I love to a tee, but this manga is just perfection. If you are feeling down or sad, this is almost certainly the cure, as I'm almost certain it could lift anyone's spirits. I am a little late on this one, 13 volumes are already out in English, but I'd recommend this to just about anyone.
