So these are some things I do when I start a language!: Start a binder. This binder is for conjugations of MAIN and essential verbs (ie: to do, to go, to want, to be able to, etc). I write down the main 3 or 4 tenses for each verb (one verb per page). Create cheat sheet notes for main and important conversation starters. What’s essential here is to understand how to ask and answer questions (ie: how are you? What do you like to do for fun? What’s your opinion of..?) Enrich your language by learning adjectives, adverbs and their placement! These are SO common in everyday speech. Then I always start reading and writing on day one. I keep a journal I write in everyday and I start reading and learning new words immediately. I also watch and listen to as much media in that language as I can. The key is INPUT and also contextual learning. Learning a whole bunch of vocab won’t help you if you don’t know how to use it! Good luck!!

Yes, you can! The first example is much more informal. I would also say “you’re out of your mind” and delete the “like”...it doesn’t work so well in that part of the sentence. The second example is much more formal, but essentially means the same as the first sentence. When I read these phrases I think, “the person saying these sentences are trying to tease, or joke with someone who did something ridiculous or crazy”, OR, “this person is genuinely worried about another person’s mental health”. Either way, they work grammatically and flow pretty well! They have different impact depending on how you use them in context :) great job!
