I am looking for a way to organize a charity event. Can you provide me with some tips on how to plan and execute it successfully? Your response should contain at least 5 sentences. Highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. In your response, the word *event* should appear at least 3 times. At the end of your response, please explicitly add a postscript starting with *P.S.*.
