Trying not to get ahead of myself

I saw the perfect job today. Literally I read the job description and I was friggin beaming all morning at just the thought of getting the job.
In my current job, I feel like I am wasting my life. It was very sad for me the first time I verbalized that sentiment - wasting my life. How sad. How utterly sad. I'm 26 years old and all I want at this stage is a career. I'm not interested in getting married or having kids, I just want to invest my time in my career. And yet, in my current position, I'm wasting my time and my talents.
The job description sounds great and when I'm doing my actual job, I love it. However, 90% of my time is not spent doing my job. It's spent doing menial tasks or surfing the net pretending to be busy. I literally ask my manager for work constantly and am not given any or I'm given the paper to read. WTF! Reading the paper is not work, it's something to do over lunch. It's sad that I want to work hard and do an exceptional job for my company but I'm not given any challenges so I feel I'm wasting my days aways pretending to work.
So of course, I've started the old job search again...looking for a new challenge. I need change. I need big change. At 26, my life has become too settled - I need to mix things up. So I've been searching for that "thing", that job, that change, that sign...whatever you want to call it. But nothing has really popped up...until today. I saw it. And when I say "it" - I mean the perfect freaking job.
The job that I would love. A job that would make me love Mondays. A job, I would quite frankly rock at. Actually, it's kind of a step down and I'm probably over qualified for it but it's in a different industry. An industry that I have no experience in so I'm trying not to get too far ahead of myself and build up my hopes too much. I need to have my resume come across in such a way that they think this girl would be great even though she has no direct experience her skills are definitely transferable.
Half of me, wants to show up in person with resume in hand and declare that I am the ideal person and the other half wants to play it cool and not let myself dream.
I'm not much of a prayer but I did find myself looking to the heavens today. ...Crossing my fingers that it all works out.............can life be that great?
