ACT is an acronym standing for Action Counters Terror. It is believed that it originated either with the military or the emergency services, where personnel are trained to overcome fear and inertia by taking action until this becomes an automatic response. ACT demonstrates that people are capable of really remarkable deeds and that obstacles and difficulties can be beaten when they are confronted. ACT shows that fears and self-doubt can be reduced or eliminated and that forward-looking action can overcome habit and inertia to produce something new and start the process of change.

It does, however, highlight that people are capable of far more than they realise, and that fears can be beaten when they are confronted. Action show fears and self-doubt as merely a question of attitude; forward-looking action overcomes habit and inertia to produce something new and is the simplest way to start the process of change.
