The moment will be fleeting, but you will get a taste for it. Then it will be gone. The goal is to bring it back so that you can be in control of the process, instead of the process controlling you. This takes practice. Tons and tons and tons of practice.
Real writing happens in the heart.
It comes from people we've known or observed, loved or hated. It comes from the best and worst moments in our lives, where we learn from a new encounter, or feel an emotion we've never experienced before. No, it simply means you've found ways that don't work. A failure today is chalked up as an experience tomorrow. And if it generates more questions, even better-every quest for the truth begins with not knowing.
