Without any experience of working as a startup, I'm not qualified for giving opinions on what people should do when making a mistake.
However, I did think about when I only read the books I wanted and ignored teacher's contemptuous, and the national entrance exam of college I got 6/100 on math and 88/100 on Chinese.
If I could breathe and think without leaving my 18-year-old life decion for my panic, furious, ashamed, and anxieous mother, maybe I could start the life that I'm now trying to achieve over 30 years.
On the contrary, if I could know brain was used for thinking logically instead of an organ, I might not be able to see many things in a different new light and have sufficient opinions to write them down.
