I love editing. I love sensing how my story or post is improving because I have taken the wasted words out. Without a decent edit (and ideally at least two to three), I know no work of mine will be accepted anywhere because I always overwrite and so have to cut out the padding. But I don't mind doing that. I like to write down all of my ideas and then select the strongest, based on my outline. It is always a relief getting that first draft down because I then know I definitely have something to work with and experience to date tells me the edit only improves a piece.
I do think it vital though to keep the creative side away from the editing side. You need that joy of creating something new to help you get that story nailed to the screen but the sensible editing side comes later. They really are two separate tasks. How can you edit something properly that isn't finished? So write first, edit later is my mantra and I've never regretted following that.
