This Week's Summary
Teaching people is ineffective; teaching a task once is enough.
People often realize their mistakes only after the fact, and when the dust settles, they are engulfed by endless regret, repeatedly chewing over the unnecessary errors.
Although this week wasn't particularly outstanding, it was passable to some extent. There is still a need for optimization and improvement. Reading a book a hundred times reveals its meaning; continuous effort and progress upwards is what should be done.
