I'm a beginner in Japanese, but I've kinda learned a bit of Japanese on and off. I was stressing myself out with the Kanji, trying to learn the basic Kanji. I didn't even learn vocabulary, I just prioritized learning basic Kanji first - which was tiring to me and I stopped. So I'm trying to prioritize vocabulary now, but I wonder if I should write them in Hiragana/Katakana instead of writing them with their Kanji?
I'm just learning really basic things right now. I'm learning with a little book "Learning Japanese in 30 days" (it's not in English; and I'm not actually learning it in 30 days, I'm taking my time) and there's no Kanji in it - it's just in Hiragana/Katakana so it's really just for building a basic understanding of talking Japanese.
It would take some more time to learn the words with Kanji (I'd just learn how to write them and pronounce them in that word, not all the pronunciations and meanings), but if I learn them without the Kanji now, it would be weird to learn the words again later on, just with their Kanji.
What do you think I should do?
Yes, it would be good to continue with the kanji!
The earlier you start the better.
Maybe just write furigana for ones you're unsure of.
