      \documentclass{article}
      \begin{document}
      \def\alist{boil water, keep calm, move to countyside, 
        carry a knife, take food, take clothes, take 3 books}
      \makeatletter
      \@for \i:=\alist \do{
        \texttt{\i $\rightarrow$ }
      }
      \makeatother
      \end{document}
