Oh, no doubt. When I was doing freelance many years ago, I actually forced myself to have my office in a specific room, that could be locked. I did that for two reasons, 1) it put me in the mindset of, I’m at work, and 2) I could lock the door when I’m done for the day to prevent me from going back in it (give the key to your wife or significant other, you’ll be amazed on how well they can hide it from you until the next work day begins).
In the end, freelance wasn’t for me. I just found myself easily distracted and I didn’t enjoy the business side of things – managing the financial aspect of it, taking care of taxes, and so forth. Though I’ve started to consider switching more to that style of work again, purely so I have even more time with the kids (I’d have to move though, as the place we have now, doesn’t have a dedicated room I can turn into an office – nor does it have the space to create one).
