Climb every mountain

Julia and Molly are on their way to math class.
　　Julia: Oh man, cheap Inflatable Obstacle this totally stinks. Why is math class on the third floor? I hate climbing up these stairs.
　　Molly: Yeah, me too. But I guess it’ll help me to lose some weight.
　　Julia: Haha, yeah, I guess.
　　Molly: Speaking of climbing, I read this article last night about a girl named Samantha Larson who climbed to the summit of Mt. Everest.
　　Julia: That’s nice, but what’s so special about that? Don’t people reach the summit all the time now?
　　Molly: Yea, but she’s eighteen years old—the same age as us! She’s the youngest foreigner to reach the summit. And not only that, she’s also the youngest person ever to climb all seven summits!
　Julia: Holy cow, that’s incredible! Wait, what’re the seven summits?
　　Molly: You know, the seven highest summits on each continent. So apparently, this girl climbed South America’s Aconcagua when she was 13! And then, she climbed Mt. Kilimanjaro when she was only 14!
　　Julia: That’s unbelievable. I can’t even stand climbing up the steps to math class!
　　Molly: Yeah, for real. But you know, it got me thinking.
　　Julia: What do you mean?
　　Molly: This girl’s determination belies her young age. Most people who attempt to scale Mt. Everest never make it to the top because of all sorts of reasons. But she didn’t give up. I mean, she successfully climbed the highest mountain on each continent.
　　Julia: Yea, that is pretty impressive.
　　Molly: So you know how the saying goes—if you set your mind to it, you can achieve anything.
　　Julia: Sure, those fortune cookie sayings are a dime a dozen.
　　Molly: Yeah, but I’m seeing more and more how true the saying is. It’s like, people don’t really achieve anything because they haven’t set their mind to anything. People wake up, with no clear purpose for their day, and just cruise along on auto-pilot.
　　Julia: Hmm, this sounds like a typical day in my life.
　　Molly: And mine, too. That’s what needs to change. I’ll bet when Samantha Larson was climbing those mountains, each day of her ascent, she envisioned herself on the summit, never losing sight of the goal.
　　Julia: But you know what, aside from losing sight of the goal, I think another reason why people underachieve is that they haven’t found anything in life that grips them the way mountain climbing grips Samantha.
　　Molly: That’s a good point.
　　Julia: My parents always tell me that I should not fear trying something new. They say that if I don’t try it, I won’t ever really know if I like it or not. I’ll bet it was the same with Samantha. I mean, she probably wasn’t born on a mountaintop!
　　Molly: I’m totally with you. You know what? I’m gonna audition for that Broadway musical that our school is putting on. It’s been a dream of mine to be a performer!
