Organisation can help in many aspects of life. Freelance writing for profit is no different. Even if you don't have a dedicated home office, you should still designate and organize an area as your work-space.
Keep reference material, office supplies and hard-files handy and close to your computer and work area. Time management is a key aspect of freelance writing for profit and the ability to quickly grab a pen or a notepad will make creating content easy and efficient.
Be sure people in the household understand that freelance writing is a job like any other. Fortunately, working from home is more common than it was a few years ago. With that said, family and friends living in the house should respect your work-hours and treat your work-space as they would an office even if it's just the kitchen table.
Efficiency is important when freelance writing for profit. Set yourself up to be as efficient as possible everyday.
