This is not to have a go at anyone else. I'm talking at myself as well, but why is it that when we only have finite time the thing we let go of is writing?
As you know I run 2 writing groups but I struggle to get people to keep coming. Most people who do give a reason say that they're too busy, that they have other commitments, etc. Ok so there are some that do just say it isn't for them but I do see some very talented writers just get "too busy" to write.
Yet I am no better. There are groups I could go to where I would be encouraged in my writing but I don't go. Why? Well … I've got the dog to walk, rooms to clean for my guests, things to do that people will notice I am doing.
I was listening to a talk by a moderately famous writer and she said that she prefers the researching because then she feels like she is really doing something, the "writing her novel" she can drag herself through but the editing, where in fact she is getting rid rather than constructing - even those we, the reader, enjoy a book much more when it has been well edited. So even when one becomes a "proper" writer it is still hard to put the writing first.
I believe the reason why more of us aren't published writers is because we don't push through that barrier that says we're too busy and writing needs to be the thing to go.
