Identify a topic about which you feel strongly and on which you would like others to follow your lead and take action. Possibilities might be climate change, employment opportunities for adolescents, bankers’ bonuses, healthy eating or something else. Then write a report for others to read which might galvanise them to action. Check that it is written in a way that will be likely to produce a positive reaction from your readership (which you may like to narrow to a specific group). Then write your Executive Summary. Give it to one or two of your friends and assess their reaction. Finally, rewrite it in the light of their responses.
