Doors are normally opened with the aid of a key , but what of if the key is lost, then the door will be open by a KICK. Some books are tittled "Seven Keys to Success ", "Ten Keys to Success " , I will tell writer to forget about key and show me the door, then I will let the door know that it is not only the key that can open it, but it can also be opened by a KICK!!! Thinking of where to kick in the door.

To save you stress, get the key
