Could you please give some advice for a Finnish author?

Dear all in bookmarketing network!

My publisher in the USA asked me to film a 1 min. videoiclip for their major campaign. I need your advice because the American reader is probably somewhat different from a Finnish reader. What do would you advise me to emphasize in my message?

My book The WInning Helix is about learning and winning.

I am grateful for all advice and hints that I can get!

Greetings from Helsinki
