The irresistible feel to immortalize moments satisfies one of our first desires, to leave a legacy, a legacy which may not necessarily be a selfie or a photo of a place you've visited for holidays. It's a portal to show others the way you see the world. In other words, you let others see the world as you do.
The moment you shut down your brain and let your instincts guide you is the moment where the fun begins, and the moment you step foot in the path to find the great beauty. Personally, it's not just about taking photos, it's about enjoying the moment, immortalizing it, and let others enjoy it too.
