I’d put it into Robinhood and buy gold ($50/yr) so it earns 4.6% while not being invested. Then do research on stocks, pick some companies you might have a passion for, or just stick with ETFs. VOO is typically your best bet, that should be your largest position, but don’t be afraid to invest in other companies that you feel will be a good investment (Apple, Microsoft, Nvidia, Tesla, T-Mobile, Berkshire Hathaway, etc)
You should absolutely do a HYSA! Emergency fund should be a top priority. I would recommend an account with fidelity/ vanguard/ Schwab for your brokerage acct/ IRA. They’re better designed for long term wealth building that robinhood which is built to encourage shorter holdings, not wealth building.
