Identify and better understand your inner character.
Although extroverted qualities are often sought out in others, it is not always necessary to display these qualities - especially if they aren’t natural! Instead, it is more important to understand who you are, and where your specific strengths lie.
Make a list of the things you are good at - and the skills associated with them
These skills can be used to develop a list of character traits and help you better understand what you are good at.
Think about where you fall on the introvert/extrovert spectrum
Do you enjoy public speaking? Do you seek out opportunities to interact with others? These questions will help you identify how much of an introvert or extrovert you are.
Update your list as you go along
As you better yourself, update your list of skills and re-assess yourself.
