Feeling intimidated yet? Feeling guilty? Unworthy? Lazy? Untalented?
Yup. Lots of writers work to a strict timetable. Lots of writers have a daily target that they meet come hell or high water. Lots of writers do it - but it doesn't mean that ALL writers have to do the same. Nor does it mean that your work will be inferior if you only produce 200 words a day (that was Graham Greene's target BTW).
Your circumstances may be different from, say Anthony Trollope who wrote 2000 words before going to his day job running the Post Office for the government. He ordered his valet to wake him up and make sure he got up and started writing, regardless of what AT said at the time.
Don't know about you, but I don't have a valet. If there's getting up early to be done, it's going to happen by will power alone. Sometimes it works - and sometimes it doesn't. I try to get 1000 words done most days, and hope for nearer 2000. When I'm on a writing retreat I can manage 3,500-4,000 words a day, because I've excluded everything else in my life.
Word counts and targets are good, but they have to be your own, not ones you've taken from someone else. Don't be intimidated because you know a prolific writer - maybe they will need to do a lot of re-writing to bring their splurge of words to the level you write at on your first draft. You've got to remember you're not in competition with anyone else. Just keep writing at a steady pace until you're done.
