Stage 1: You upload videos on YouTube for fun

Stage 2: You upload videos on Youtube often, so now you decide to make it your hobby

Stage 3: You became a full-time YouTuber you upload videos for money, as well as getting used to editing

Stage 4: You decided that whatever you make can get a lot of views regardless, so you stopped trying. And your mental state *could* gradually change based on the type of content on your channel.

Stage 5: You randomly stopped uploading, or announced that you're gonna stop uploading for a long time. Hopefully you've gotten a job, or a proper life, or at least slightly improve yourself while you're gone, otherwise a lot of bad things can happen to you, and you can possibly be a subject of a stereotypical YouTuber documentary.
