I’ve found having a good group of friends will help. It increases your social circle and gives you more opportunities to meet people, or have them meet people for you. I’d say that most of my relationships have been people that my friends have met that they thought I might like, or someone I met at a party my friends had invited me to. The best way to meet people is to make sure you happen upon enough people ;-)
Although I’m married now, and I met my husband at work. So maybe I’m not the best person to answer the question.
Although if you are looking to hook up and “meet” people. I think it’s all Online for the most part now ;-)
