The only limit to our realization of tomorrow is our doubts of today.

译文：爽口的美食吃多了容易生病，高兴的事过头容易生出祸殃。赏析：任何看似令人爽口的食物吃多了，都会伤害身体，更何况那些垃圾食品呢。人在高兴时，容易得意忘形，说话做事都有失妥当。

The more you can create a world that feels real, the more the audience will be drawn into it.

解释：处在有利的地位上想到道义，处在困难之中想到保持纯正。

最重要的是保持头脑活跃。
