It's all about expanding your network. If you don't go out, you don't get to meet other people.
Clubs are usually for extroverts; dating apps are useful for introverts.
Typically, people meet at school/work. So for the singles out there, need to expand your horizon for more chances of winning! :D
For me, finding your true love has nothing to do where you meet. I don't believe in one true love, but I do believe in perfect matching. So need to choose wisely. :)
