There are two points here.
The first is, literally, write where you are.
You don’t need a magic desk, or a sea view, or the sound of migrating Elk – to be honest I don’t even know if Elk migrate, but you get the point I’m sure.
Write in a notebook, write on your phone, write on your arm.
Keep your brain on its creative channel and don’t switch over to see what is on the other side.
I’m still learning this lesson.
The second point is, write where you are. Write from your thoughts, your experiences, the voices of the characters standing next to you.
Sometimes the people reading you will love it. Sometimes they won’t.
It’s like your favourite band. You don’t like every album they’ve ever made. Well not the same anyway.
You have preferred albums. This one blew your mind. That one made you wonder is a cover band made it because the original band members were still drinking cocktails in Tahiti.
They were writing where they were.
That’s all they could do. They could only write what was there with them at that moment in time.
That is all you can do too.
Some people will think it is your best work ever. Others will wonder if you are still in Tahiti.
So write where you are. (Which might actually be Tahiti!)
