your problem like mine...
when i came to web design area, i confused what i want to build. So i just build one website with multi languages fill about computer related article. but, i got bored. And then something came to my mind. Why i dont make website which bring me profit like money or something like that ? but about what...? so i'm starting to looking around and still no found anything interest me. When my husband looked me like that.. he told me to build what i like, or what i need to learn. if you now in progress learning about some program so build about that. if you now learning about fashion so build about fashion website. And about the money.. it will come if you can fullfill what you learn. Because good website with good content and complete content, will bring money it self.
So because now i'm pregnant, i decided to make a pregnant website. And im still in progress to make it completed.
That's my suggestion to you... just build what you want or your hobby, see the topic from your life, your Environment (sorry my english so bad)
