3. Delegate And Postpone
Once you’ve identified an interruption as something that needs attention and not just a nascent longing to goof off, try to postpone your involvement. The brute way of doing this is to shout out, “I don’t have time right now. Don’t bother me!”

The classy option is a bit more involved. Take a moment to understand what the distraction involves. Is somebody dying? Is there a deadline you’ve forgotten? Is there a networking opportunity here? If it turns out that you’re not facing an emergency, postpone your involvement and delegate as much of the detail work to somebody with available resources.
委托或者推迟
如果你的计划被一件复杂的事给绊住了，很难脱身，如果不是很急或必须你来完成的事的话，试着交给其他人去完成。
