Being socialable is a very easy thing to do, and it shouldn’t be something you’re either good at or not. You can learn to become a more social person - if you want to.
Generally extroverts will have less trouble getting out and talking to new people, but that’s to be expected. Don’t think, however, that outgoing people don’t make mistakes either. There are ways to make life easier while you’re out and about.
Don’t feel like you have to do anything. You’re out for your own reasons and want to do your own thing. Different things work for different people. For instance, you might never feel comfortable approaching strangers. Find your own groove and be yourself.
