Today, I listened to part of the book "This World is Both Cruel and Gentle" while riding my bike. Here are a few simple summaries:

1. The ability to think independently and make decisions from a young age is really important. Sun's parents let him make his own decisions from a young age and bear the consequences of his choices.

2. There's nothing wrong with not liking a routine life; be brave to explore.

3. Improve your ability to participate in social competition from all dimensions.
