瘋狂學習難度：☆☆☆☆
1. We Are Responsible for Our Life. And nobody else. Although all success requires the assistance and cooperation of others, our success can never be left to anyone else. Luck is not a strategy.
我們要對我們的人生負責。這不是別人的責任。盡管所有的成功都需要別人的幫助與合作，但我們的成功不能依賴別人來替我們取得。等待好運降臨并非上策。
2. Life is Short. Whether we live 20 years or 100, our lives pass quickly. All the more reason to spend our life doing what we love. Since we never know how much time we have left, we should live each day as if it is our last—for it just may be.
人生短暫。不管我們活到20歲還是100歲，我們的人生都過得很快。所以我們更加要在有生之年做自己熱愛的事情。既然我們還剩多少時日都是未知的，我們應該把每一天當成自己的最后一天來過——況且很有這個可能。
3. You Can’t Learn Less. We can only add to our knowledge. We don’t have to give some of it up in exchange for new knowledge. Our ability to absorb and retain knowledge may just be unlimited.
知識只會越學越多。我們只會增加我們的知識。我們不用放棄一些知識來交換新的知識。我們吸收和掌握知識的能力很可能是無限的。
4. Clarity Leads to Power. When we’re clear, we’re more effective. Our clarity reduces our mistakes and enables us to enlist the help of others. We are more powerful when we are clear, and we are weaker when we are confused.
思路清晰能夠產生能量。當我們思路清晰時，我們的效率會更高。清晰的思維能夠減少我們的錯誤，并爭取到別人的幫助。當我們思路清晰時，我們就更加強大；當我們煩惱困惑時，我們則變得弱小。
5. What You Sow, You Reap. This is also called The Law of the Farm or The Law of Reciprocity. In order to continue to receive, we must give.
種瓜得瓜，種豆得豆。這叫農場定律，也叫回報定律。如果你想繼續(xù)獲得，你就要學會付出。
6. You Can’t Un-ring a Bell. No one can change what’s already happened. Whatever is done is done. It’s up to us whether we use the experience to learn or allow ourselves to be run by the experience.
覆水難收。事情既已發(fā)生，誰也無法改變。木已成舟，夫復奈何？我們是從事情中吸取教訓，還是一直為其所困，這些都取決于我們自己。
7. It Takes a Long Time to Build a Good Reputation and Only a Short While to Ruin It. Trust and credibility is built slowly but can be lost almost instantly.
信譽建難毀易。信任和聲譽是慢慢建立起來的，但卻能毀于一旦。
8. If You Don’t Believe in Yourself, No One Else Will. People don’t respect or follow anyone who doesn’t have confidence in themselves. I think the Universe tends to trust us to the degree we trust ourselves.
如果你不相信自己，沒有人會相信你。人們是不會尊重或者追隨那些沒有自信的人的。我認為，你有多自信，世界就有多相信你。
9. It Doesn’t Take Guts to Quit. Anyone can quit. And most people do—on their dreams and on themselves．
放棄并不需要勇氣。每個都可以放棄。而且大部分也在這么做——放棄夢想和放棄自我。
10. We Can Accomplish Anything We Want, Just Not EVERYTHING We Want. It’s too big a world. There are too many options, too many things and only a certain amount of time.
我們能夠完成任何我們想做的事情，但不是所有的事情。世界這么大，有太多的選擇，太多的事情，而我們只有有限的時間。
