Yesterday is history,Tomorrow is a mystery and Today is a gift.

Imagine life as a game in which you are juggling some five balls in the air.You name them--work,family,health,friends and spirit,and you are keeping all these balls in the air.
You understand that work is a rubber ball.If you drop it,it will bounce back.But the other balls are made of glass.If you drop one of these,it will be irrevocably scuffed,marked,nicked,damaged or even shattered..They will never be the same .You must understand that and strive for balance in your life.How?
Don't undermine your worth by comparing yourself to others.It is because we are different that each of us is special.Don't set your goals by what other people think important.Only you know what is best for you.Don't take for granted the things closest to your heart.Cling to them as you would to life,for without them,it's meaningless.Don't let your life slip through your fingers by living in the past or in the future.By living your life one day at a time,you live all the days of your live. Don't run through life so fast that you forget not only where you've been,but also where you are going.Don't use time or words carelessly.Neither can be retrieved.Life is not a race,but a journey to be savored each step of the way.Yesterday is history,tomorrow is mystery,and today is a gift.That's why we call it--The Present.

可以把生命想象成一场抛球杂技，你用手抛向空中的5个球分别叫做：工作、家庭、健康、朋友和精神。

工作是个橡皮球，如果你不慎失手，它掉到地上以后还会反弹回来。但其余4个都是玻璃球，一旦落地，轻则留下永久的缺口，重则粉身碎骨，无可挽回。所以我们必须学会在生活中寻求平衡。那么该怎么做呢？

不要在和别人的比较中否定自己的价值，因为我们互不相同，每个人都是一个独特的个体。不要把别人的价值观作为自己的追逐目标，只有你自己清楚什么最适合你。不要忽视最接近你心灵的东西，要像珍惜生命一样珍惜它们，因为它们才是生命真正的意义所在。不要总活在过去和未来里，却让生命轻易地从指间流走，试着一心一意地活在今天，你就抓住了生命中的每一天。不要一生只顾匆匆奔走，这样你最终会不知何去何从。不要草率地对待时间和话语，因为它们都如覆水难收。生命不是一场赛跑，而是一个每一步都值得体味的旅程。昨天已成为历史，明天仍不可预知，今天才是生命的厚礼。这就是为什么我们称之为——The Present（现在/礼物）。(zt)
