In humble opinion, house hacking is the single greatest way to get into real estate investing, if you're able to do it. Buy a small multifamily, live in one side, rent out the other to long term tenants. Or, do the same, furnish the other unit(s) and rent them out as short term or corporate rentals if your municipality allows it.
Beyond that, begin with the end in mind! What do you want your life to look like once your stratgey is up and running? The life of a house flipper is VERY different from the life of a note investor or an apartment syndicator. They also take different skills, more or less money to get started, etc.
If you're able, find a strategy that interests you and seek to "intern" at it for a period. Offer your time (for free or mostly for free) to an experienced investor doing that strategy.
This does two things: 1. Gives you experience executing that strategy alongside someone with more experience. 2. Gives you a taste of what life is like for someone doing that strategy. You may find that the money is good, but the life it provides is not what you're looking for.
Good luck!
