When I 1st got obsessed I spent every bit of money I had on buying DVDs never bothered so much with manga but dabbled not as much as I wanted. I didn't think about cost at the start either I just wanted to get every thing.
At some point I tried learning Japanese on my own with the internet but could never find a source that would teach me in the easiest way I was used to learning and thought some where might of done it but never found it
a system of giving you a set amount of information asking question and tests to do with the information then repeating the process with previous information needed as well. I did this kind of thing at school and it really helps to absorb information I got so used to it that at some point I had a photographic memory for words I would only have to read it once and I should remember it for a week. I can't do it any more though I've not been in education for so long that I've dumbed down
I always thought of retrying and if I ever managed it I thought I should make the site that I always thought would of helped me to learn Japanese.
I'm still a bit obsessed I'm interested in creating my own manga with my friend he's mostly the story writer and I'm mostly the artist but I'm not great at creating some thing quickly I need to be inspired to get it going. Never had the big idea either to push things along (well a few but they have always been the kind of stories I love at the start and hate at the end).
If I ever get a job I've always thought of starting to get some series memorabilia like figures and stuff.
The only thing I've never thought of doing was going to Japan though which most people seem to do.
