I'm not sure what you are trying to find but the one that comes to mind is Vitamin.
There is also Taiyou no Ie but that's only because i can relate to the protagonist so i am unsure whether or not it's inspiring.
Well I'm looking for any manga thats worth reading. Anything fine other than yaoi
Just read it.
When someone says "just read it" it means they really liked it. I'll defn give it a try
