生活因为希望才快乐

We should hope for the best, but prepare for the worst. The worst result is that we can't get out of the world alive. Someday I hope to have a whole complex of caves. If at first you don't succeed, try, try, again. If it still doesn't work, redefine success. All you need in this life is ignorance and confidence; then success is sure. is full of ups and downs, especially when you're an elevator operator. Life is a sum of all your choices. Life is like an onion: youpeel off（脱掉）layer after layer and then you find there is nothing in it. Life is like surfing, you might catch a good wave and have a fun ride, but watch out for those sharks. Don't take life too seriously - you won't get out alive. When life throws you stones, throw them back!
