The write time.
Your voice comes from the inside and is independent of your environment. As a writer you must learn to connect with your voice no matter the circumstances.
When starting out as a writer, you are always looking for the right time and place to write. The perfect setting and moment where everything comes together, and you express yourself with divine elegance and supernatural depth.
You seek that moment, and try to design it the best you can. Depending on who you are, you either go for solitude and silence, or the nearest café to absorb the atmosphere and turn it into something on the page.
You start having little rituals that you must perform before writing, and you might even start demanding a certain behavior from people around you, when you are in writing mode.
