None of us are trying to stop you. Most people who go into Japanese thinking it will be easy give up when they find out it's not. We just want to make sure you are prepared so you don't give up.

Hehe thanks dude for ur concern, but i realy do want to learn it :D

OK, the first thing to do is learn katakana and hiragana.

After that, here's what I suggested in another thread as, in my experience, the ideal (or at least a very effective) program for learning Japanese:

and what about Japanese learning tapes...? thats what im useing.
i can already say quite a bit... the tapes are teaching me the basics. there are 90 tapes of 30 minutes each - they teach u sentences and word order, and there's also bonus tapes that teach u words. so if i learn those tapes well - like i hav (im only on the 4th tape because i replay it until i know it off by heart) then i should be able to move on to gramma like u say.
but i dont think moving on to gramma straight away is very wise...

The sooner you start learning grammar the better. You will move from being someone who can repeat a tape-recording to someone who can think in Japanese.
