Do you like things to happen quickly?
If so, you can use the expression, “As soon as possible,” to tell someone to do something very quickly.
You can also use it to tell someone you’ll do something very quickly.
Girl: Do you want to have a drink with me this Sunday?
Boy: I might be busy. I’ll let you know as soon as possible if I’m free.
A husband calling his wife: Hello Alice. Please call me as soon as possible.
Adam: John, please get here as soon as possible.
John: Okay. I’m coming right now.
We also say A.S.A.P (As Soon As Possible)
Boss: I need this work done A.S.A.P.
