I have thought about getting an office, but figured out I just needed to tackle some issues at home to make my home office the perfect fit for me.
If you need an office to " get out of the house", that makes no sense to me. If I want to get out of the house, I go somewhere and find something to do. It's sad if your entire existence is tied to work in some way and without a structured work environment you have nothing you enjoy doing ( even if what you enjoy is lounging around not doing anything).
Maybe it's because I "got out" of the corporate environment before I ever really got sucked in, but all the supposed benefits of working in an office are many of the reasons I work for myself.
I would consider getting an office if it meant I could get work done better and more efficiently. It would also require no or almost no commute, no meals out, socializing, or any of that bullshit,etc.
