Have you ever thought about your dreams and how some feel unattainable?

Definitely, it can be really discouraging sometimes.

Yeah, I mean, it's okay to have big goals, but some just seem so far away.

True! But maybe we can break them down into smaller steps to make them more achievable.

Root Explanation
Unattainable → It is formed from "un-" (meaning not) and "attain" (from Old French *atteindre*, meaning to reach or achieve) and "-able" (meaning capable of). The word "unattainable" means not capable of being reached or achieved.
Memory Tip
Think of 'not' ('un-') being able to 'reach' ('attain') something — that's why unattainable means something you cannot reach.
