Limiting the no of times a macro can run

Dear All

I am looking for a code which shall limit the no of times a macro can be run.

Say I am using this undermentioned simple code:-

 
Sub PasteSpecialValue()
Selection.Value = Selection.Value
End Sub

I want that, say, after having this code run for x (10) times EVER , the code just does nothing....i.e it becomes inoperative/ ineffective when I am trying to run for 11th time. Here "x" can be set to any number.
Thanx
