Working from home for the forseeable future. There's something to be said for this and I think it's the hardest part of running a business or really doing anything at all that requries multiple people, but the actual human act of exchanging information is the single hardest thing there is in the universe. It's not something actively consider that often but holy shit is it hard. 

When you're working in a place and you can't just open your mouth and expel the information it just breaks down instantly. It cannot be done in any meaninful way when you're balancing more than one project. It's a nightmare. There's no software to fix this.
