You take a test. Don't like the results. You have the power to nullify it. You run for office and lose. You overturn the results and?

You declare you won of course.

How would you like that power? Y=

You don't like how a book ends you sue the author and force him/her to write the ending you want.

So you have the power to get any result you want at any time. Not only involving you and your attempts but everyone else too. Say you are the KINGMAKER/QUEENMAKER of the entire world. What you say goes. No one has ruled the entire world before. YOU ARE FIRST TO DO SO.
