@Squirtle how old are you?
1. I'd get debt free as soon as possible. Dave Ramsey's 7 baby steps is a good method but it depends on your income and debt level.
2. I'd max out your 401k. Then get a Roth IRA. Max that out too. I'll add a link to a few good ones or you can select the one that's best for you. I'd have a liquid cash emergency fund on stash in a HYSA before investing though.
3. Stock market is a good option too. If you want to get your feet wet, download the robinhood app just to get started and play around with maybe $100 or so.
I don't know if you have debt but I had to learn the hard way...wasted a few years of my life in CC debt
I also read a lot of financial books so if you need some of those let me know and I have YouTube links in podcast but it's doable no matter your salary.
I hate debt and I am very frugal so I'm always trying to learn more.
