How can I socialize when my life is boring and unimpressive?

My life is boring. I’m unemployed. My future is bleak. I have no major accomplishments to brag about. My love life is nonexistent. I’m not involved in any team, committee, etc. I live in my father’s house. I’m basically a lowlife.
How can I successfully socialize, when I can’t really talk about myself? There’s literally nothing interesting or enticing about the details of my existence.
