Make decisions when you are ready, not under pressure. Others will always push you to make a decision for their own purposes, internal politics, or some other external need. But you can almost always say, “I need a little more time to think about this. I’ll get back to you.” This tactic is very effective at defusing even the most difficult and uncomfortable situations.

I never look back. I look forward to the next challenge.

释义：要了解过去和现在，以便灵活应变，适应变化。
