Over the past few weeks I've made an effort to put myself in more social situations and surround myself with people when I'd typically be alone. If there's one thing I've learned it's that everyone would rather be socializing than doing almost anything. Unless someone is experiencing something really emotional or is totally repulsed by you, they'd prefer a casual social interaction with a new person to just about anything. Just start a simple conversation and see where it goes. Even if it doesn't progress, it's good practice.
