O ambicioso versus o desejoso (parte II)

Parte I.

"I've seldom met a successful person who didn't start out with a set of ambitious goals. However, the power of goal-setting isn't just anecdotal. It turns out that there's a wealth of scientific research into how goal-setting changes the way you brain functions. That research also provides guidance on how to make goal-setting vastly more effective.
.
Here's the gist: Goal-setting restructures your brain to make it more effective.
...
goals that are highly emotional (i.e., the subject is highly motivated to succeed) cause participants to downwardly evaluate the difficulty of achieving that goal.
.
In other words, if you strongly desire a goal, your brain will perceive obstacles as less significant than they might otherwise appear.
...
Research has also shown that ambitious goals are far more motivating (i.e. they more thorougly structure your brain) than easily achieved goals.
...
In other words, if you want to fully activate your amygdala and frontal lobe so that your brain makes you more successful, you must set challenging goals.
...
In 90% of the studies, specific and challenging goals led to higher performance than easy goals, "do your best" goals, or no goals. Goals affect performance by directing attention, mobilizing effort, increasing persistence, and motivating strategy development. Goal setting is most likely to improve task performance when the goals are specific and sufficiently challenging."
