                                                                                                      Ways to save time

    We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring­clean the house, or write your novel, or learn the guitar and so on.

    ____But I can help you find more hours in your day for the things that really matter.

    Get Out of Bed Earlier

    If you normally get up at 7:30 am, try getting up at 7:00 am. That half­hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish.____

    Do the Important Tasks First

    Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.____The urgent tasks will still get done, and you won't miss the important ones.

    Reduce Interruptions

    If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter. Constant interruptions don't just eat up time, they also break your concentration.When you've got a big task to focus on, let your calls go to voicemail.____  Wearing headphones makes it less likely that people will try to strike up a conversation.

    ____

    A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day.

    When you're working, work. If your concentration is slipping, take a proper break, go and get a glass of water, or stretch your legs a bit. And if you're facing a difficult task, try breaking it into small steps or stages so that it's easier to deal with.

A. Or simply to get your day off to a calm and organized start.

B. I can't magically make all your days 25 hours long.

C. Would you want me to make your day longer?

D. Take Breaks When Necessary

E. If you have an office door, close it.

F. If you work like this, you'll usually save time.

G. Stay Focused on Your Work

       ①总爱一个人悄悄翻开一本诗词集,时光就极静极静地拂着面颊,流过。心沉醉在长短句中,好舒适。于是就有了一个好舒适的名字——境界。
       ②进入了“境界”,长短句就有了一种音乐流程般的美。读来,满口噙香。顺着音乐流出的是:如七弦古琴的低低哀诉,如吴侬软语的绵绵温柔,如朔风胡马的悲壮,如大漠风沙的豪迈。深山古寺的空灵,天地一沙鸥的浩渺,江湖夜雨的漂泊,银鞍白马的飘逸,尽融于此境界中。
        ③心中印满了诗词,以至稍有触动,就要出来。窗外下雨——“幕雨萧条过凤城,霏霏飒飒重还轻”“雨滴梧桐秋夜长,愁心和雨到昭阳。”点燃一盏孤灯——“落叶他乡村,孤灯独夜人”“白发无情侵老境,青灯有味似儿时。”皓月当空——“深林人不知,明月来相照”“今人不见古时月,今月曾经照古人”。每天发生在身边的事何止听雨、观灯、弄月?于是都在诗词的感觉中度过。心细腻到了极点,就会变得多愁善感,如那位林妹妹。花开花谢,草青草黄,雁来雁往,都能惹人洒几滴泪珠。然而就在悲伤的一刹间,又感觉一种诗词境界的美,它的名字叫忧郁。
       ④在古诗词中,好像那流传千古的名句中都有一丝淡淡的忧郁。“丁香空结雨中愁”“一江春水向东流”“人比黄花瘦”,莫不如此。当读到这些诗词时,细细吟诵品味,于是心也沉浸在这种氛围中了,好像自己就是那位红楼怨女、天涯游子。
        ⑤爱品味这种忧郁的滋味,也喜爱那些悲凉的怨歌。如马致远的“枯藤老树昏鸦,小桥流水人家,古道西风瘦马。夕阳西下,断肠人在天涯”。每句话都是一幅画,每幅画都能引发人的许多联想。读它,就如同在清冷月光下长吟,幽深、清远又寂寥。
        ⑥常有人问我:“你工作之余的生活是什么?”我说:“读古诗词。”于是,一种异样的眼光就无可回避地落在我身上了。古诗词太静,太遥远,静得有些枯燥,遥远得又捉摸不定,但可爱的就是这静,就是这遥远,静中却能激起心上的惊涛骇浪,遥远却能向你心中更深处靠近。
        ⑦当一本本诗集词集刻在脑中,诗词的精华也融于精神中,忽然发现:不管是在象牙塔内还是飘然于塔外,只要我爱,时光就会静静地流过,拂过面颊。
        ⑧身外有个世界,杂乱纷繁的世界。心中有个世界,古诗词的世界,静静的,静静的……
