There are a lot of misconceptions about what being introverted means, and it's not an "anti-social" behavior. Introverts are regenerated and energized by spending time alone, and often prefer solitude to group activities, which many introverts find emotionally taxing.  Anti-social personality disorder is more akin to psychopathy or sociopathy, and refers to an inability to empathize or emotionally connect with others. Truly anti-social people are often ego-driven and superficially charming in ways that correspond more with a traditional view of extroversion.  There is nothing wrong with introversion, and although many self-help books and get-rich guides suggest that extroversion is the key to happiness and wealth, there's no evidence to suggest that one personality trait is more productive or successful than the other. Both personality types can be creative and productive in the right working environment. " While many introverts may be said to be "shy" in public, this isn't necessarily the case, and it's important to learn the difference. Introversion is not a measure of shyness, just as extroversion means more than "being outgoing."  Shyness refers to a fear of speaking out in group situations and failing to communicate with others, and a preference for solitude based on this fear. Introverts prefer solitude because working alone is more stimulating than working with others, and social interactions may be more taxing than exciting for the introvert. Introverts aren't necessarily "scared" to interact with others, they are just unenthusiastic about it. Are you energized by the thought of spending time alone? Would you rather work on a project alone, or collaborate with others? In a group situation, would it drive you crazy to not contribute your thoughts, or would you rather save your opinions for a side conversation?  Generally speaking, you don't "become" an introvert by changing your behaviors, because there's little point in spending more time alone if you don't enjoy it, or it doesn't stimulate you creatively. Pay attention to your own tendencies and foster them. If you think you're extroverted, there's no reason to try to change yourself. Instead, give yourself a more social work environment to be productive. A person doesn't have to be clearly in one or the other "camp." Ambiversion is a term used to describe people who move comfortably between the two ends of the personality spectrum, and a great many people actually score somewhere in the 50/50 range on personality tests. Try taking a Myers-Briggs personality test to learn more about how you score in the personality department, and what this might tell you about how to foster your traits and give yourself the best chance for success, given your unique qualities and desires.

Summary:
Distinguish between introversion and anti-social behavior. Distinguish between introversion and being "shy. Pay attention to what excites you. Look beyond the dichotomy.
