I'll get right on that.

behind: 뒤에, 뒤로

leave st behind => ~를 두고 오다, 깜빡하다.

behind schedule => 일정보다 늦어진

fall behind: 뒤처지다. 

---------------------------------------------

We are behind / with the wedding preparations. 

[우리 지금 결혼식 준비가 늦어지고 있어요.]

I was late so I ran as fast as I could.

I will ask them to restore the data as fast as they can.

---------------------------------------------

Go get the table centerpieces.

             테이블 중앙 장식품

[any decoration you put in the center of a table.]

--------------------------------------------

And when you are done, tell the crew to bring in the bow for the chairs.                

bow: 활, 리본

---------------------------------------------

assign: ~를 부여하다

---------------------------------------------

I would've never put the big projects until the end of the semester.

"Now, get right on this because you don't want the deadline sneaking up on you.

         (어느새 모르게 코 앞으로 다가 오다.)

I didn't mean to sneak up on you.

---------------------------------------------

So I wish I could go back in time and just do the projects right away, get started on them right away.

=> go back in time: 시간을 되돌리다. 

I wish I could go back in time and do things differently.

---------------------------------------------

so that I would be less stressed out at the end of every semester.

At the end of every month, we throw a small party.
