- Now I've been sort of banging on about this for the last couple of months,
- 在过去的几个月里，我反复在讨论这个问题，
- and people sometimes say to me, "Well Tim, it's kind of obvious. Obviously trial and error is very important.
- 有时有人跟我说：“提姆，这不是很显然么，很显然试验和排除错误很重要，
- Obviously experimentation is very important. Now why are you just wandering around saying this obvious thing?"
- 很显然尝试很重要。你为什么到处讲这个显而易见的事情呢？”

- I will admit it's obvious when schools start teaching children that there are some problems that don't have a correct answer.
- 当学校开始告诉孩子们，有时问题不总是有正确答案的时候，我会承认这很显然。

- And if you can't find the answers, you must be lazy or stupid.
