22 year old trying to change my life

Hello, I’m 22 years old and my goal is to have a successful Amazon business. I want to start small selling mugs, socks, brushes, etc. just small items. I want to eventually graduate to private labeling. What should I do to get started, my goal is to have Amazon replace my job. I wanna make enough money to support myself and my business to allow it to grow. I plan on quitting my job once I can get my Amazon account to generate 4x my reg income. Any advice in e-commerce in general is appreciated, I just wanna get started so I can do more for my family.
