Joke aside, just stay consistent by studying your schedules, stick mainly to words and grammar and you should see progress. Ofc start with Katakana and Hiragana first if you haven't already.
Once you have a good base vocabulary you can start reading small articles in Japanese or stories on sites like Tadoku.org
it’s hard to give more specific advice without knowing what level you are at? are you at the very beginning of your japanese learning journey? do you know a few hundred words? a few thousand?..
Without any judgment, with 100 words and basic grammar, your biggest target should be lots of memorization just like everyone above has said.
Right now you want to be using a spaced repetition software like Renshuu to increase that vocabulary and as soon as you feel comfortable, you can start immersing and mining for new vocabulary and grammar. Most people find it easiest to start immersion when they have anywhere from 1K words at the low end to several thousand at the high end.
With only 100 words, I'm not sure there's anything I can really recommend for immersion, outside of maybe listening immersion to help you understand the sound of the language better (but in that case you're not really immersing to learn the language so much as learning the right sounds without meaning).
Take notes of what you’ve learned, memorize it down (doesn’t have to be perfect but the get generally ~80% down) and also take breaks. Don’t focus on studying everyday since that ruins your memorization skills and forces you to stress to learn more. Japanese content can also help
I'd recommend immersion to get accustomed to the language in use instead of just textbook studying, that way it'd be easier to develop an "instinct" for the language + you'll feel better when you recognise what you studied out in the wild, which is great motivation. Passive learning is important too!
There is a app for reading articles and simple stories called yomu yomu , it's pretty simple and kinda limited but there are ofc other, better ones to use and practice reading from. Hope this helped somewhat
Try listening to more japanese songs or dramas! I know many people say anime uses more informal japanese, and isn't helpful, but just learning the words and memorizing it is harder than knowing where to use it.
What I'm trying to say, is that seeing a character apologize for their mistake and saying "Sumimasen" sticks with you more than knowing the word "Sumimasen" and learning its meaning.
