“First few steps” is a pretty broad designation so sorry if some of this is elementary.
The first step of anything in life, IMO, is to have zero credit card debt. Then save enough money to cover ~2 months of expenses. Then contribute enough to your 401k to maximize any employer match (but not more) in some 2060ish target fund. (At this point, I’d recommend reviewing any debt (esp car) >4% and weigh refi vs payoff.) Then bump savings enough to cover ~5 months of expenses and put it in an online savings performance account (roughly 1.7%).
Once you achieve those things, I’d open a zero commission brokerage account. I don’t have an advisor because I deal largely in financial statement analysis and I don’t want one because this is a hobby for me as well, but there are lots of options out there if you do want one.
A lot of people tell you to start with index funds but screw that. Your entire 401k is essentially in index funds. I would recommend establishing a solid base of consistent performing/dividend paying companies with strong balance sheets. I use nasdaq to research dividend history - amounts, frequency, length, historically consistent and continually raising. Also important to research payout coverage on higher yielding investments to be alerted to potential dividend cuts. Reinvest dividends.
After that base is established, you can get into more speculative plays in tech, fintech or biotech/med. There are larger more established guys and startups waiting to pop on some development. All different areas to explore. My largest piece of advice is to just consume as much information as possible.
