20 galleries in 20 weeks

Building another 100-day habit:


  • Review 1 Storytelling With Data challenge gallery per week.
  • Pick 1 submission per weekday and tweet its link. Identify:
    • 1 effective / theft-worthy feature
    • 1 idea for improvement
    • A takeaway title
  • Stick to time budget of 15–30 minutes per day, before 10:30 PM Eastern


  1. Critiquing models—for both strengths and weaknesses—is one of my most effective learning habits: in writing, teaching writing, UI design… so why not also dataviz unto data stories?
  2. I will learn more by practicing this habit frequently.
  3. Continuing this habit over 20 weeks will build a nice collection of 100+ models that I can revisit in future.
  4. Building this collection on Twitter will force me to be pithy while turning that account to good use (given that I prefer personal communication but see the value of making work visible online).
  5. Sticking to clear time limits will help me prioritize (get to the point faster!).


Each Saturday, write a mini-recap in my wrex (30–45 minutes). Flexible week to week:

  • Pick 5 ahead of time or as I go?
  • Include 0, 1, or 2 additional selections in my mini-recap?
  • Read recap by SWD team before, during, after, or not at all?
  • Take an extra 1–3 hours and try the challenge myself?


SWD currently has 39 challenges online, 1 per month from January 2018 onward. The next 20 weeks will add another 5, for April through August. Here are my top 5+5 of current interest:

Pick a small reward for each 25-day milestone! Worked well with my CollectUI-browsing habit in 2019/2020 (e.g. buy an ebook I’ve wanted).
