I’m glad you found the inspiration and motivation to keep writing because I’ve found many of your posts to be very helpful and equally motivating to me.
Speaking directly to the principle you share, it’s also very liberating when you feel like you don’t know a subject very well to realize you are better off for it. Better off being a student of it. And actually, now that I think about it more, I realize how well this fits into a growth mindset. Brilliant!
