I think the big question you have to answer for yourself is why things haven’t worked out for you. Is it a pleasant experience to have a conversation with you? Do you often talk to people in general? Do you smell good or horrible? Do you generally take responsibility for your life as much as could be expected for someone in your situation? Are there any underlying mental health or attachment issues that need to be addressed? Do you give people a sense of safety, or do they get vibes of racism or misogyny from you, or vibes that you might abuse them? There is no deadline for addressing any of these besides the big deadline, being dead. But they are all better addressed sooner rather than later, to the extent you can. Besides that, you need to make yourself available to be dated.
