Yeah, that is right. You need to write everyday because if you don't your pencil lead will get rusty and you'll have a harder time getting those ideas down.
Even if you don't write towards your novel you can still journal, write your feelings, what you did that day. You don't even need a computer or your rusty pencil, you can use your phone. And all you need is 10 minutes, 5 minutes, or 2 minutes. Just write something. While you’re waiting in the carpool line, waiting in line at the grocery store, or use a talk to text app on your phone while you’re doing the dishes.
There are so many ways and chances for you to write, you just need to get into the habit of doing it. If you are waiting you should be writing. If you are doing something that requires no thought then you should be writing.
Now, what are you doing just sitting there staring at this, get to work!
