9.More People Are Leaving the Rat Race for the Simple LifeTime is more precious than money for an increasing number of people who are choosing to live more with less-and liking it.
Kay and Charles Giddens,two lawyers,sold their home to start a B&B hotel.Four years later,the couple dishes out banana pancake breakfast,cleans toilets and serves homemade chocolate chip cookies to guests in a B&B hotel surrounded by trees on a hill known for colorful sunsets.
"Do I miss the freeways?Do I miss the traffic?Do I miss the stress?No,"says Ms.Giddens,"This is a phenomenon that's fairly wide spread.A lot of people are reevaluating their lives and figuring out what they want to do.If their base is being damaged,what's the payoff?"
Simple living ranges from cutting down on weeknight activities to sharing housing,living closer to work,avoiding shopping malls,borrowing books from the library instead of buying them,and taking a cut in pay to work at a more pleasurable job.
Vicki Robin,a writer,lives on a budget equal to a fifth of what she used to make."You become conscious about where your money is going and how valuable it is,"Ms.Robin says,"You tend not to use things up.You cook at home rather than eat out…"
Janet Luhrs,a lawyer,quit her job after giving birth and leaving her daughter with a nanny for two weeks."It was not the way I wanted to raise my kids,"she says,"Simplicity is not just about saving money; it's about me sitting down every night with my kids to a candlelit dinner with classical music."
Mrs.Luhrs now edits a magazine,Simple Living,which publishes tips on how to buy recycled furniture and shoes,organize potluck dinners instead of expensive receptions,and generally how to consume less.
"It's not about poverty,"Mrs.Luhrs explains,"It's about conscious living and creating the life you want.The less stuff you buy,the less money goes out of the door,and the less money you have to earn."

16.Life is difficult.
    It is great truth because once we truly understand and accept it,then life is no longer difficult.
 Most do not fully see this truth.Instead,they complain about their problems and difficulties as if life should be easy.It seems to them that difficulties represent a special kind of suffering especially forced upon them or upon their familie s,their class,or even their nation.
 What makes life difficult is that the process of facing and solving problems is a painful one.Problems,depending on their nature,cause us sadness,loneliness or regret or anger and fear.These are uncomfortable feelings,often as painful as any kind of physical pain.And since life causes an endless series of problems,life is always difficult and is full of pain as well as joy.
Yet,it is in this whole process of solving problems that life has its meaning.Problems are the serious tests that tell us success from failure. When we desire to encourage the growth of human spirit,we encourage the human ability to solve problems,just as in school we set problems for our children to solve.It is through the pain of meeting and working out problems that we learn.As Benjamin Franklin said,"Those things that hurt instruct."It is for this reason that wise people learn not to fear but to welcome the pain of problems.

6.The well-known adventurer and explorer Steve Fossett was famous for extraordinary efforts in setting world records in flying,ballooning and sailing.He set or broke over 100records in five different sports.Many of these records still hold.
Steve Fossett was born in 1944in Jackson,Tennessee.At twelve,he climbed his first mountain,and he kept going by choosing bigger and bigger goals.During his life,Fossett climbed the highest mountain on every continent except Mount Everest.
Also in 1985,he became the 270th person to swim across the English Channel.In 1991Fossett decided to pursue the highest goals in ballooning and sailing.Steve Fossett attempted the hot-air balloon trip around the world six times.This was not easy to do.During his fourth attempt in 1998,he was almost killed during a thunderstorm off the coast of Australia.Fossett successfully made the trip in 2002.He traveled over 33,000kilometers for over 14days.On this fight,Fosstt set other records including a speed record of 322kilometers per hour.

Steve Fossett once said that he did not like risks.He knew this might sound strange considering his activities.But he said what he tried to do was reduce risk with careful planning,technological development and the help of the best scientists and other experts.
Yet,no amount of planning can prevent the possibility of risk in life.In September of 2007,during a short-distance flight,his plane disappeared.At last,in February of 2008,a judge in Chicago declared Steve Fossett legally dead.He was sixty-three years old.
