On this 2nd day of NaNoWriMo do these three things now to set yourself up for success.
Set yourself up for success.
Sometimes first-time NaNo writers give up before they really get started.
Decide that you want to succeed
It's a daily commitment and it's going to take a lot of your time and effort. Writing 1667 words per day will get you there. Writing more than that will get you there faster.
Set aside enough time to write
It goes without saying that you can't succeed if you don't give yourself sufficient time to do so. You may have to give up something that you're doing in your day to day that is not moving you toward your writing goal. That habit may be eating up some valuable time that you could use to get your word count up to the daily limit.
You may need to set some other non-essential tasks aside, at least temporarily, so that you can focus on your writing.
Write at the best time of day for you
It can be self-defeating when you set a goal to wake up to write at 4:30 each morning when you know you're not a morning person. Also, vice versa. Don't try to do everything that you can do in a day and then leave yourself a few minutes at the end of the day where you have to try to speed write to get your word count when you're already exhausted. You want to find a happy medium there. You may need to experiment a little bit to find that happy medium but once you find it, do your best to stick with it for the best results.
What time of day works best for you? Morning, afternoon, or evening?
