完形填空的句子理解
I should know.I have been doing this for 20 years.Why is it that I need a sign to remind me?
Every other week in my neighborhood we place either recycled bottles or paper out with our garbage.There is a sign alongside the road that says “This is bin week” or “This is paper week”．The schedule is simply changed every other week.But I can never remember which week is which.Every week,I make an effort to look for the sign.
There was a period a few months ago when no one changed the sign.
I had mixed emotions.I was confused,angry and concerned.Confused because I didn’t know what to do.Annoyed because someone should have changed it!Concerned because,after relying on that “someone” for almost twenty years,I worried that perhaps something had happened to that “someone”．
Then,yesterday I finally saw the man who replaced the sign.I slowed down and wanted to tell him how much I appreciated what he did.I couldn’t stop in time because I found that the traffic sign said “The Next Exit Is 2km”．So I drove as the traffic sign indicated.
By the time I got back,the man was gone.I felt so regretful.I should have stopped alongside the road and just said “thank you”．I pulled over in front of the sign and thought about how many times in my life I looked for a sign to tell me what to do.I was reminded that all too often I missed an opportunity because I was looking for a sign.Today I wanted to tell “someone” how valuable I think their efforts are but missed the opportunity.
So,I wrote a note and placed it next to the sign.
If you have been hesitating to move forward towards a dream,say thanks to someone who lends you a hand,or begin a new project,this may be the sign you’ve been looking for.
The note says,“This is do it now week.”
上面文章中倒数第二段If you have been hesitating to move forward towards a dream,say thanks to someone who lends you a hand,or begin a new project,this may be the sign you’ve been looking for.中的this指的是什么啊?另外这句话怎么翻译啊?

1、this译为"这",指的是The note—“This is do it now week".
2、翻译：如果你还在犹豫着而无法梦乡迈进,向对你伸出帮助之手的人说谢谢,或者开始一个新的项目,这或许就是你一直在找的路标.
