Keep busy.
I don’t like to spend my days doing nothing, so I write. I’ve been asked how I can knock out 100,000 words in a couple of months, and that’s how: by writing. Every day, for as long as it takes. No weekends. No holidays.
I used to get pushback from writers who’d say things like, “I can’t write two thousand words a day!” Or whatever number you choose to insert, as if it’s the number of words that makes the difference and not the routine. You could write 250 words a day, and in a little over a year, you’d have 100,000 words of your own written. There’s no magic formula here, only steady work.
These days, I tend to write anywhere from 1,250 to 2,000 words a day. More sometimes, but never less. It takes me somewhere between one and two hours to get that done, but that’s because I’ve had lots of practice. If you stick to that regimen of 250 words I just mentioned, you’ll find yourself able to pack more writing into smaller and smaller periods. You might end up being even faster than me! Some people certainly are.
Consistency is key. Even if you decide you only want to write, say, 125 words a day, that’s fine, but write those words every. Single. Day. Don’t make excuses why you can’t because missing a day means missing another day and another and another. You’ll never form a habit that way, and this is the kind of habit you want to have.
