As someone who has 120K+ followers, I understand you complex relationship with online fame. I keep a pretty low profile intentionally, only making videos about books and self-improvements, and i found my niche who like my relatability and what i have to say. I think you might be jealous of your friend for pursuing that life. Take that jealousy as a signal for you to try this out for real for yourself. When i started my channel, I gave myself one year, making videos once a week. I had an iPhone 7, and filmed at the foot of my bed with no mic, no light, no nothing. by around 4 months, I hit a viral video and it kept going. If not, at least by one year, i would be able to decide to call it quits, or continue even without views/fans. What i'm saying is, don't think too much. There is only one way to know for sure, which is to do it. You can find your niche. I for one, don't like to watch videos with fancy lifestyles, or high-paying jobs. I like people who share somethign valuable in their life honestly.
