Hello, everyone. Are you introverts? Trust me! There are millions of introverts around the world that can totally relate to your feelings and experiences. Introverts are everywhere, but they often go unnoticed. If it feels like no one around you can understand introversion, take heart in knowing that there are millions of introverts with experience the same things you do.
    You don’t raise your hand in class or speak up at work because you think that everything you say must be profound and flawless. You carefully filter your words and feel enormous pressure to say the right things.
    You usually don’t talk much. Sometimes you don’t know what to say, other times you don’t have anything to say, and still other times you just don’t have the energy to talk.(23)Regardless, you still wish people would take more time to get to know you, or you wish you had more energy to talk to them.
    When meeting a group of new people, you try your best to give a good first impression and appear sociable. Eventually, however, you lose people’s attention because small talk isn’t your strong suit and you can’t think of anything good to say. As you continue to feel invisible, you beat yourself up or feel you’re uninteresting or lack charisma(魅力).
     (24)You don’t like to be in the spotlight and letting people into your home is a big deal for you. It almost feels like they’re invading your sanctuary. As a result, you rarely, if ever, throw parties at your place. When you do, you’re reluctant to invite people you aren’t extremely close to. When your friends ask if they can bring a guest, you’re forced to say yes even though it makes you anxious.
     (25)You could be standing in a room full of people but you still feel isolated and out of place. You crave deep conversations, but all you get is small talk. You consider yourself lucky if you find someone to talk to in the corner of the room.
    If you have to spend a day or more with new coworkers or classmates you feel completely wiped out by the time you’re done. By the time the day ends, there’s only one thing on your mind: going home and enjoying some alone time. Finally! You often wonder why these situations are so much more draining for you than they are for other people, and you wish you were more outgoing and energetic.
    Thanks for listening!
