No problem! If you are short on time and don’t want to spend a lot of energy hunting for quality articles, the two best website I would recommend are Longreads and Longform which are longform content aggregators.
As a personal recommendation, I am also partial to WaitButWhy which I find not only informative but also hilarious.
Finally if you want to see the list of sources I am currently use (constantly being edited), I just made my Google Doc public as well.
Longreads features the best storytelling on the web from hundreds of publishers. Story picks include longform…longreads.com
Longform.org posts great new and classic non-fiction articles, curated from across the web.longform.org
