1. It requires a ton of discipline
I have never struggled so much to get myself to actually just sit down and write. When you are studying, you have to work each day because you have impending deadlines, if you are just starting to write your first novel and do not have an agent, you do not have set deadlines. You can try setting deadlines for yourself but I have found that I do not always write the same number of words in each setting and to push myself to meet word counts may mean that the quality of writing is not as good and I just scrap what I have written anyway. Instead, I now set myself to write on certain days and have a minimum word goal I would like to achieve in mind.
