Do you set out your stall out to write at certain times on a particular day? Feel annoyed, and irritated if it doesn't happen? Don't - you'll save yourself a lot heartache and stress. Its best not to feel guilty about missing a writing session if it was out of your control.
Be flexible, re plan, or if that isn't possible, relax, and focus on the next session you have planned. Sometimes as writers, we need to stop and think about what we've achieved so far. Don't wreck your motivation, because you've missed one session. It won't help you get that book finished.
Don't overwork yourself, it really is counter productive, instead be gentle with yourself, if you're tired you won't write well, once your brain starts to feel fuzzy, or you feel your eyelids closing, its time to quit. Get some rest and recharge. If you don't, your motivation for working the next day will be poor, and you'll end up getting less done. Its much better to be flexible.
Do you have a set writing schedule? What do you do if you miss it?
