As a self-aware introvert nothing gets me more excited then some downtime: preferably alone! Yet my daily work, especially as a game developer, often involves collaborative effort with others, which I enjoy. It just means that it’s important for me to take time to recharge after a day full of people-ing.
Also, don’t confuse shyness with introvertism (which is unfortunately a very common mistake), as extroverts can be shy as well. Conversely introverts can be out-going. The between shyness on introvertism is that shy people are afraid or have anxiety in certain, if not all, social situations; whereas introverts can be comfortable in social situations but need to recharge when they are on their own. While extroverts get recharged by being around others and can be drained when isolated. Thus you can have outgoing introverts (like me!), or shy extroverts (like some of my friends who prefer to hang out on the edges of social gatherings but prefer to be there around others, unlike an introvert who would probably prefer to be home with a book, or a video game, or napping, and gets super excited when the party gets canceled!). However, unlike the introvert/extrovert scale which seems to remain pretty much the same for people throughout their lives, shyness doesn’t have to be a constant in your life! You can overcome it! You can be formerly-shy!
So don’t let labels — given to you by others or yourself — hold you back from all God intended for you. Recognize where your energy comes from so you can recharge on your journey, and then go after your dream with all your gusto!
