If there is one thing that I've learned it is that there are shallow introverts. Talkative introverts. Social anxiety riddled extroverts. Deep poetically reserved Extroverts.
Its simply where people get their energy. For some extroverts, we only need one person to feel like we can go accomplish something.
But this is a far stretch from being able to lock myself in my tower for 5 days with a good book and feel okay about it.
I like to express my ideas emotions and creativity with others and I can't just hide it all inside and feel accomplished.
And for me, that is how I know I'm an extrovert. When I get into a discussion I pick up steam and enthusiasm. I feed off of the inspirations that other people provide and I give it back hoping that they can do the same for me, until we have truly achieved something great.
I like taking the facts, drawing a relationship between them and then showing how it all fits into the big picture. Because at the end of the day whether we are introverted or extroverted, we are all connected and there is a sort of beautiful complexity to it. Like the entangling bonds of DNA, only its personality and its in all of us.
