Such an obvious truth, and so profound.
For the writer, the takeaway is dead simple.
Think about your writer friends. (You have writer friends, right? If not, get on that. Really. Like, now.) If your writer friends are the kind of people who seem to enjoy bitching about the writing process, don’t be surprised when your own writing times become very unfun.
The voices of the people around you shape how you see the world. That’s true in writing and in life.
Surround yourself with the kind of people who make your life better.
