I lost some time once. It’s always in the last place you look for it. – Neil Gaiman
Do you have enough self discipline to write? It is so easy to lose track of time and find yourself halfway through the day before you have written anything outside of answering emails and making a grocery list. Try setting a schedule for yourself and stick to it. Even if you can do it for a week that will help set you into the pattern and the second week will be easier.
