Hi, Terry!
I've got a few suggestions.
First, I'd lose all the dashes. You don't need them. What are you hearing when you write them...do they take the place of an imaginary drum roll? If so, then I'd rewrite. Maybe try exclamation points instead.
This is it! Your chance to...blah blah...
Now there's something that jars me a bit. It's the voice. Can you rewrite the letter exactly the way you talk? I mean, if you were standing in my kitchen telling me about your new discovery, you would never say, "I am about to show you how." Or "I remember being in the same situation..."
I think there are times when we do want to write a bit more formally, but writing to an audience of informal young people wouldn't be it.
Actually, I think you could lose "I am about to show you how" altogether.
I like the sentence, "I played on that damn thing every chance I got." That's good. Very informal and descriptive. Exactly the kind of thing you'd say in person to a friend.
"Until one day when I just could not afford it anymore." Can you make a story out of that? Can you show me what it was like, instead of telling me? Here's a story I thought of ...I'm sure you could do better:
There was this girl I had my eye on. Long wavy golden hair, huge green eyes, and a body like Beyonce. Way out of my league, but a man can dream, right? Well, one day a friend talked me into helping him with a paper at the library. We walked in the front door, and who was there, right in front of us, but my Dream Girl.
We struck up a conversation, and I asked her out for that weekend. I was so excited. Until I realized that I'd spent my last 50 bucks on games.
Damn.
I was either gonna have to ask my parents for money or cancel the date.
Anyway, maybe not that long, and not that example, but maybe if you can illustrate not being able to afford something so the reader feels the pain. Ya know, make it visceral.
Couple of grammar things --
its instead of
it's. (It's is the contraction for it is.) I
saw or I
had seen instead of I
seen. I
sank or I
had sunk instead of I
sunk.
I'd also like to see the section on "is this book for me" a lot earlier in the letter. I think you can delete the lines below it "the best way to answer this question is to ask you a series of small questions."
That just slows the reader down -- go ahead and launch into the bullets.
The more I think about it, the more I think maybe most of the background could either disappear altogether or be significantly shortened. But I'm not sure about that...
Anyway, my suggestions could be boiled down to voice and action. If you hit the right voice, writing the way you speak, and delete anything that slows the reader down, get it fast-paced from the start, I think it would improve the letter.
I'm sure others will have different viewpoints. It'll be fun to see what they say.
All the best -- by the way, you've really done quite well with this -- I especially like the way you use your headlines and subheads. Just a little more tweaking and you'll have a killer letter on your hands.
