Today’s read pages 44-54, sections 18 & 19.
Short sweet and simple:
Whatever you create in life be it write, paint, dance, or… someone at some point will ‘constructively’ suggest that you can do better, thus implying you didn’t do well and with that one may feel shame.
Don’t. Don’t ever be ashamed of anything you create. If you briefly do, make it brief and don’t carry the shame. It’s all part of the creative process, even if it wasn’t your best or flat out wasn’t good. It is what will get you to the next thing and the next level, as long as you don’t let shame get you down.

Great book about life, so many lessons. There are a couple of great sections just ahead for you.
“someone at some point will ‘constructively’ suggest that you can do better, thus implying you didn’t do well and with that one may feel shame”
it depends on the circumstance and how the words are said. for example, if it’s my boss, he can show me a way to do something more efficiently and I am grateful and learn something. if someone is criticizing my knitting in a snotty way, I ask them if they can knit; if they say no, I tell them to fuck off.
