Set yourself a goal. Many authors have a daily goal. "I will write two pages a day". Or "I will write 2000 words a day". Do this every day and you will get your novel in under a year.
A page can be defined as opening Microsoft Word and writing on a 8.5 x 11 in paper with default margins, single spaced. Two pages like this is about 1,000 words. If you need to type in double spaced format, it would be four pages.
To key is to do it everyday. If at first you can't hit two pages, the goal is trying to become consistent and get something, anything on the page. Once you consistently get something on the page every day, go for one page, then whatever goal you're aiming for.
