Final answer:
The actions/will power stage involves individuals committing to a behavioral change through an action plan, aligning with their SMART goals and requiring a determined mindset.
Step-by-step explanation:
The actions/will power stage is when individuals commit to making a behavioral change and enact a(n) action plan. This stage is crucial because it involves a tangible commitment on the part of the individuals to change their thinking and behaviors in pursuit of their SMART (Specific, Measurable, Achievable, Relevant, and Time-bound) goals.
