When it comes to goals, using "ranges" can be incredibly helpful.
It's the difference between:
As you can see, one is quite definitive, while the other one provides some buffer.
But why would you want to make a distinction like this?
The secret lies in people's different approaches to learning, applying, and setting goals. As we've been discussing throughout the book, there are different approaches to goal-setting. As such, when formulating your goal, you need to take into consideration the type of goal, your own personal style, and whether it makes sense to use a range or not.
This could be the equivalent of going "all-in" (Goal #1) or "partial" (Goal #2). The all-in approach is great for those who like the all-or-nothing approach, while the latter suits personality types that are slower, more steady, and may be satisfied with slight variations in success rates (e.g. I'm fine if I lose around 30lbs).
Either way, the use of ranges can turn you from being discouraged (e.g. if you're seeking to achieve a goal but fail to hit it exactly the way you envisioned it) to being highly motivated (now knowing that even if you shoot for the stars, you'll still land on the moon). It's a suble, yet significant, psychological difference that goes a long way in matching your own personal preferences.
