Answer:
Setting long-term goals will assist in how a person thinks, it sets a mentality of hard work and will to reach said goals, for example, a person that sets learning a language and is determinted to learn the language will eventually learn it.
It's how long-term goals change someone's ability to think of something, it's easier when it's stretched, and more desirable when someone has the will to land that dream job or dream position they're after.
