I invariably write in a more focused, sustained way when I'm away from home: pre-Covid, I often worked in our local library, and I've sometimes hit as many as 10,000 words from 2pm - 11pm while on a writing retreat at a local hotel.
If you struggle with procrastination or a lack of focus, or if you never seem to find the time to write, it could be because of your writing environment.
Are you trying to write at home, with distractions all around (family members, chores to be done, meals to prepare, a steady internet connection...)?
If so, and if Covid regulations in your country permit, try getting away and writing somewhere new for at least a couple of hours.
You'll instantly eliminate a lot of the distractions (tip: turn off your laptop's wifi and silence your phone) and the act of setting aside time like this also makes it easier to sit down and just focus on writing.
Even if you do need to work from home, you might want to try working in different parts of the house. Perhaps you simply can't concentrate when you try to sit on the sofa and write ... but you find it much easier to focus if you're upstairs, working at a little desk in your bedroom. Maybe the kitchen table never seems to work as a writing location ... but your garden shed could be perfect.
You can also improve your writing environment as part of your writing session. Try spending the first 5 minutes of your writing time tidying up your desk: this can help you ease into writing mode and also reduce distractions.
