Hello. I am self-teaching myself some Japanese, but I am having trouble with some things. I first started teaching myself some easy introduction words, months, #s, etc., (but those are all in romaji). Things like that, but now I think I should start studying on the hiragana, katakana, and kanji (One at a time of course). I have concerns:

1) What is the difference between these three? Sush as its common use? Please explain and add examples? . . . I read some definitions of these three, but I am still puzzled. <-- This is my biggest issue. There is so much information I may have to read on these, but many of them use big words and/or explain too much, when I just need a simple explanation. I can't learn the grammar of Japanese unless I understand these, right?

2) Which one should I start on first do you recommend?

Someone please help me.

Thank you!
