Horizon and Digital Ocean

RethinkDB has a new product they're launching in a couple weeks- Horizon. It's been quite the experience branding it and switching gears to do RethinkDB AND this new product. I'm learning a lot about my skillz, where they are weak and where they are strong, as well as my capacity to manage multiple projects at one time. What tools do you use to manage your time and projects? Asana? Trello? Paper calendar? Naps?
