When I first got into real estate, it was through books like Rich Dad Poor Dad. I started talking about Real Estate with others and then met my current business partner while he was fixing my sink and were talking about real estate. From there, we joined the local REIA, took classes there, and networked with others. We made some good connections there, which helped us tremendously. Word of caution with REIAs. Go more for the networking and information, but don't get sucked into the pitches. Many guest speakers brought into the one we are members of are looking to sell their "system" to you. You can listen to the talk because you will usually learn something, but you don't need the system they are pitching most of the time.
I'm all for attending local meetups, as most here have mentioned but also talking about your interests freely to others (you never know who is listening). If you don't have a local meetup, start one. There are many ways to do this. I'm more of a meet-in-person type, but virtual can also be great (especially if you are looking at other markets to invest in). Your mind is the main factor here. If you want to achieve something and believe it in your heart, you will make it happen.
