I just want to make money online. But i don't know what kind of things are online. Any ideas?

I just want to make QUICK FAST money with zero investment just sitting at home in my comfort zone. I have tried many things. freelance (photoshop, videos editing, music mixing, digital marketing, SEO, insatgram marketing, language transform), blogging, making and selling music, youtube, stock trade. I am just tired i get no return. I spend so much time, money and effort to learn so many skills but i am going nowhere. I am getting money from my father's business but i actaully dont want that for long run. I just want to sit home in from of my pc and earn. And earn FAST because i dont have time for certain reason.

PLEASE HELP ME WITH SOME LEGIT IDEA. PLEASE. THANK YOU
