Personally, I love Naruto. It's very uplifting & encouraging for me. I tend to identify with alot of the characters, the whole underdog theme. Alot of the characters, have their quirks, but, in the end, they show their worth, & how strong & important they really are. It's also really funny & wacky at times.
Samurai Champloo was pretty uplifting & happy at times, had alot of wacky stuff in it, even though it's partly serious. The Galaxy Angel's are also pretty good IIRC.
Other's worth checking out:
All Purpose Cultural Cat Girl Nuku Nuku(any of them)
Tenchi Muyo(any of them, though, I havne't seen the latest series)
