You could find an interesting activity. It could be a hobby. It could be a part-time small business. It must be something YOU find really interesting, and which plenty of other people find really interesting and spend a lot of time doing or working. Then go to meetings or activities pertaining to that. At the meetings, you and the others don't mainly talk about yourselves (which is pretty boring), but about the thing you are all interested in. It could be:

-The Civil War
-Off road bicycling
-Republican Party activism
-Democrat Party activism
-Green Party activism
-Vegan eating
-Running marathons
-Martial arts
-Science fiction
-Fiction writing
-Local theater acting
-Playwriting
-Beekeeping
-Dogs
-Hamsters
-Gardening
-Whatever!

The main idea is to not talk much about yourself at all, but to talk about the fascinating things/subject/activity that you and a bunch of other people find fascinating!
