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 spring-clean the house, or write your novel, or learn the guitar and so on.

小题1:  But I can help you find more hours in your day for the things that really matter.

1.Get Out of Bed Earlier

If you normally get up at 7; 30 a.m.try getting up at 7:00 a.m.That half-hour 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.小题2: 

2.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.

小题3: The urgent tasks will still get done, and you won't miss the important ones.

3.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.小题4: Wearing headphones makes it less likely that people will try to strike up a conversation.

4. 小题5: 

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.Stay Focused on Your Work

B.Take Breaks When Necessary

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

D.If you work like this, you'll usually save time.E.Would you want me to make your day longer?

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

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