Incorrect. Good try though. You're also a random guy on the Internet. Don't forget that.
Majority of new writers do not have the capacity to write everyday. Doing so will cause burnout, strain, and may cause a negative effect. People who write everyday are actual authors with lives dedicated to stories and make a living writing. Your regular newbie writer is not that.
Get into the habit of writing regularly and set goals for yourself. But write when you can. Don't force yourself if you can't. Find a day or timeframe that fits in your schedule and dedicate that time block to your writing. As a normal human being with a full time job and other obligations, that's when you should focus on writing.
Sounds good, doesn't work. Maybe it works for you. That's awesome.
But for the vast majority of people, it doesn't. You'll write a paragraph or even a chapter and then say "I'll write when I can!" Fast forward several weeks, you haven't written a single word. Just like everything in life, consistency is important even in hobbies. It doesn't matter if it's writing, playing a sport or an instrument, learning a language, or even drawing.
You need practice and consistency to improve and find the drive to continue doing the activity. No one will improve at anything by doing it once a month or an even more sporadic schedule.
You can see this in real time with EMPIRICAL evidence next month when all the gyms get flooded with New Years Resolutioners. They'll sign up, work out for a session, then say "I'll work out again next week!" Come next week, guess what? They don't work out. Now what? They'll tell themselves "It's just one missed week, let's do next week." They don't. "I'll work out when I can!" They won't.
Consistency is the most important thing in improving and actually
finishing what you started. You don't need to write a chapter every day. You don't even need to write a paragraph. Just write a sentence if you're that burned out, or maybe write something
different than what you're currently stumped on. It's like muscle mass: if you don't use it, you'll lose it.
People who write everyday are actual authors with lives dedicated to stories and make a living writing.
Not true. I write every day and I definitely do not make a living. If you know some kind of hidden stash I've somehow been accumulating without my knowledge, please let me know. I would love to be making $5k/month on Patreon doing nothing other than publishing a ~2k word chapter every day.
