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)
Outlaw Star
Chobits(though, I've only watched a few episodes so far)
Cromartie High School(complete randomness)
Trigun(one of my absolute fav. series)
Dragon Half
Full Metal Panic(some of it is dark)
Gate Keepers(I recall being very pleased with this anime)
Happy Lesson

Last Exile(can be dark at times I suppose)
Love Hina
Martian Successor Nadesico(the series is great, the movie is darker)
