The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!
恐龙灭绝是因为它们没有太空计划。如果我们因为没有太空计划而灭绝，那是我们活该！
Sometimes the hardest thing and the right thing are the same.
Your rising from bed every morning will give fear its chance to grow stronger just as it will afford faith its chance to blossom. You will make the choice to react to one or create the other.

译文：志向不能不高远，志向不高元，就会被世俗所污染，不会有大作为；心气不能太大，心气过高，就会好高骛远，难有作为。赏析：做人要立志高远，志向远大，目标才明确，但做事不能好高骛远，眼高手低，否则，事情就会半途而废。大事做不来，小事不愿意做，是很多人通病。一个人的成功都是从小事做起，做基层做起，只有厚积才能薄发。
