Power or Service?

This week our president kid with the Costa Rica's president telling that he went to Gabon to learn how to be mantained in power 34 years and be re-elected. Bad kid for a man too close to Hugo Chavez (president of Venezuela)
In a newspaper I saw a very nice letter to our president:

"Mr. president, you were not elected to be in power, but to lead and govern a great Nation"

I don't like our president, I know he has a great history, but his party once looked like very ethic, now, as long as they are doing as bad as other people acted in government they look now hypocrit.
With this kid, we can learn other lesson: why are you leading, to have power or to serve?
