I use a website/app called Orchestra for my to-do lists. I've seen a lot of people write that to-do lists don't work, but they do for me. Planning out what exactly I needed to get done when I would sit down to work on OKDJ was important for me. I was also very goal oriented. I tackled building the company is phases: assembling the team, building the site, gathering content etc. And I would list out what needed to get done at each of those phases.
