College Student, Make around 200 dollars a week, Want to mindlessy invest 40 dollars every week into ETFs or stocks

As said in the title I'm a college student and have around 4000 dollars saved up rn and I want to start investing and I'm thinking about investing 40 dollars a week around 20 percent of my pay check into stocks to get started but I'm not sure what to invest in. I hold 2 shares of schb concurrently to get me started and some invdia, apple and intel just to get my feet wet. But if I wanted not to worry about anything and just invest in a stock or ETF what would it be? RN I'm thinking about investing 20 dollars in SCHB and 20 dollars into VOO but I want advice from people who have more experience
