Here’s a neat trick. When you’re at a party, meetup or other social event, don’t approach people standing alone. Instead, approach people in groups of two, say hello (or give a quick little glass tink ‘cheers’) and introduce yourself. A large large amount of the time, one of those two people want OUT of the conversation and you’ll be that out.

That’s a great low risk drill to get started. It’s low risk because it works and you’re in an environment where respectful interruptions like that are acceptable. Good luck and if you get stuck, feel free to reach out.
