3 concrete tips:

1. Express ideas as explanations

   1. Say how an action will transform a situation or capability, and why that action

   2. NOT : subjective opinion about importance (loose actions / goals)

2. Avoid positive arguments

   1. Arguments appeal to authority

3. Encourage alternative ideas

   1. What other actions could lead to the same goal

   2. What other better goals can be achieved via these actions ?
