Journalism and Financial Struggles

I want to start a business, but I have faced numerous challenges in the past. My parents threatened to throw me out when I didn't get results, so I moved out with little money and lived on $1,000 per month. However, the place I moved to had bedbugs and low internet speeds, which hindered my work. I moved back home because my parents wanted me back and I could focus better there. Now, I still can't trust that they support me in focusing on my business. I looked for a job for two months, made a lot of effort, and nobody took me. I made a video to showcase my editing skills, which took me two weeks to complete. Everyone said it was good, but ultimately, three guys declined to hire me, and I'm still waiting for a response from the third guy, but I have no expectations. My brother suggested I do this work for myself, and I thought, if I work for months, why not on my own YouTube channel? I already had one, but I need 4,000 watch hours for monetization, and I currently have 3,000. Now I have three options: 1. Start my business immediately, and if I get homeless, I can use social services to stay afloat and keep working, even if it will be slowly for my business. 2. Make YouTube my job and use the platform to promote my business, but I don't know how long it will take. 3. Keep looking for a job until I find one so I'm safe and can keep working on my business. What should I do?
