There are a few places I like to write:

There is this little dingy cafe near where I live and I like to steal the back booth on a Saturday morning, order a hot chocolate and write.

I take a notebook down to the park if its a nice day and jot down ideas - I find it hard to write anything concrete this way as I prefer to have my laptop to write with.

I carry and notepad and pen EVERYWHERE. You never know when you will be inspired.
