Dating Over Thirty

Hey everyone. I suppose I can be the first post in this community haha I am/have been frustrated with online dating and, supposedly, it only gets harder in your 30s. What are some general pieces of advice that I could take since I am 29 and on the cusp of joining this age-bracket? I have had some short-term relationships and have dated a lot since 2017 or so, but I don't feel like I'm much closer to finding any long-term success. I could answer more questions about myself if need be. Any and all questions or comments are welcome. You have all been pretty chill on lemmy.world.
