Common Private Sub

I have 25 same sheets and in everyone is included same Private Sub for cursor
movement.

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
If Target.Address = "$G$8" Then
Range("C9").Select
End If
..
..
..
If Target.Address = "$D$32" Then
Range("I3").Select
End If
End Sub

How can I use this macro as one for all sheets to reduce size of file.

Thanks in advance.
