Life seems to nibble away at writing time. For almost all my adult life, I’ve been in a serious relationship. I’ve owned and/or maintained my own home. I’ve always supported myself. No kids, but pets, gardens, gaming... I love to read. All huge time eaters.But no matter how drawn I am to these other things, I write. When I had another full-time job, I wrote seven days a week. Now that writing is my full-time job, I write five. This holds even when I have a “working weekend” doing book events or conventions.
Writing gets priority.
If there's anything that successful (for whatever value of that you like) writers agree on, it seems to be this: there's no substitute for the butt-in-chair time. Steal it if you have to, because only writing is writing.
