Let me tell you something, let me tell you a secret. Let me tell that how are Introverts so content.
When life hits you hard, let it be a break up, someone’s departure or anything, don’t try to suppress it and be normal and joyous again. That’s foolishness, that’s naive. No, instead breathe it in, let it fill your lungs and then your blood, let it fill you with its gloominess. It’s not depressing, in fact; it’s nourishing. It might be a life time offer, so don’t let it go, cherish it, as we do.
Being sad opens your brain to more. So, be sad, don’t be ashamed of it, because you have earned the right to it. And when you have done that, you’ll be more happy and very much alive. So once in your whole life, listen to yourself and live with your own existence.
