I can feel your frustration. People can be convinced, they can
still believe in something but don't act on their belief. Why? For
many reasons: they maybe scared, lack the means, don't know how to
act, need encouragement, and the list goes on. The most important
thing is not to prematurely judge them as lazy (they can be after
all).
In the book Call to Action (from comuneq.com) you can learn more
about how you can make your audience act (of course after you've
convinced them).
If you want them to act repeatedly or continuously, you need
them to get in the habit of acting. In this case, you need to use a
more advanced technique called the Influencing Technique. You can
learn this technique in the book Influence with Poise.
