[Why do YouTube videos only update once every 7-10 days? - Reply to private message] 1️⃣ Because it's incredibly time-consuming, and I have a slight obsessive-compulsive disorder: ⓵ I don't want any typos. ⓶ And then I have to edit them myself. 2️⃣ "YouTube videos bring in almost no income." 3️⃣ So why do I still do it? ⓵ For the "friends who follow me on Twitter" to learn from. ⓶ I'm committed to long-termism and wait for the flowers to bloom.
