Your time, that is.
Keeping your writing time sacred is hard.
Even when your network of friends and family understands and respects your time, it's hard. I'm not talking about your mom calling to see if you want to go to lunch though. You're the only one who knows the situation behind the request. Sometimes moms just know it's time for you to take a break and you should probably listen - unless you're on a major deadline, but then maybe that's why she called you - because she just knows you need a break. But like I said, I'm not talking about that.
Forget about people who want you to volunteer for stuff - they will never understand and it's probably best if you don't even mention why you can't help cut labels apart for their fundraising program, or why you can't come in to scrape stickers off the lunchroom floor. Now before you get the wrong impression, I'm totally for helping out, but it's on my terms, not theirs. I'm telling you - once you say yes to some ridiculous request once, it never ends. Believe me, I've been there. I'm not really talking about that either, though.
What I'm talking about is YOU sabotaging yourself.
Stop talking on the phone and get to work. Stop looking at the pile of papers on your desk and get to work. Stop thinking about the laundry, the bills, the dust on the piano - just get to work. And for crying out loud, stop playing games. You're going to be mad at yourself.
Yeah, there's a time for all of that stuff, but when you know you only have a determined amount of time before writing is no longer going to go uninterrupted, then seriously - stop goofing off and get to work.
This has been your reminder!
