22 year old trying to figure out what to invest in.

As the title reads I’m a young lad looking to live comfortably in the next 30-40 years. What would you recommend? I’ve seen lots of people online say the stock market is a good place to start and all these etfs like voo are the way to go. I’m just not too sure what to do so I thought I’d ask the “professionals” to help guide me. Thank you for your answers in advance!
