Most Helpful Girl
Pursue any activity that pertains to your interests. If you're doing something you enjoy, there's a better chance of meeting someone who is interested in the same things as you.
For example, if you like to cook, go to a farmer's market to buy fresh ingredients. If you like to read, go to a bookstore and browse.
Whatever you do, don't act desperate or like you're there just to pick up. If you're having a good time, people are more likely to want to talk to you.
