I create a blank page using
\newcommand\blankpage{ %comando pagina vuota
\null
\thispagestyle{empty}%
\addtocounter{page}{-1}%
\newpage}
Here it is one my page:
\thispagestyle{empty}
\addtocounter{page}{-1}
\null\vspace{\stretch{1}}
\begin{flushright}
\emph{Stay hungry, \\
stay foolish. \\}
\smallskip
Steve Jobs, Stanford University, 2005
\end{flushright}
\vspace{\stretch{5}}\null
Unfortunately adding \blankpage after that page, it doesn't work
