Need some help with this opening line

Here’s what I posted yesterday… BTW, I changed the first sentence just as I put it up and can see how poorly it reads.
“Until the day I got the picture, I wouldn’t have been able to come up with one thing I’d change about my life. I wouldn’t change my career. I wouldn’t change my boyfriend. I wouldn’t even change a thing about myself.
For that brief moment in time, I felt like my life was moving on a fast track towards perfection.
Of course, it didn’t last. Once I had the blasted picture in my hand and seared into my brain, all of my good feelings came to a screeching halt. The fast track became the tangled track and perfection became chaos and confusion, suspicion and doubt. "

I got some great feedback, a suggestion to eliminate some of the “wouldn’t" and, of course, the “have been able to come up with” and it gives a much better flow…
"Until the day I got the picture, I wouldn't have changed one thing about my life. I wouldn't have changed my career, or my boyfriend, or even myself."
For that brief…”

Unfortunately, although a great suggestion, when I put that into my story, it didn’t work. It just didn't make the point strong enough.
It’s my opening line and the story is about my character feeling on top of the world until she gets this picture . The picture triggers deep rooted insecurities that she thought she was over. The next thing she knows, all she can think about is making changes to herself. And, as a result, her whole world starts to fall apart.
I need the opening to be very specific that my character is happy with everything in her life and especially that she is happy with herself. And, I really need the statement that she wouldn’t change a thing about herself to stand out.

Here was my original and, while it doesn’t have the “have been able to come up with,” it still has all of the “wouldn’t’“…
Until the day I got the picture, I would have been pressed to come up with even one thing I’d change about my life. I wouldn’t change my career. I wouldn’t change my boyfriend. I wouldn’t even change a thing about myself.
For that brief…”

I’ve also tried…
“Until the day I got the picture, I wouldn’t have changed one thing about my life. I wouldn’t change my career, my boyfriend. I wouldn’t even change a thing about myself.
For that brief…”
Still a lot of “wouldn’t

Although the story deals with insecurities and human weaknesses, it is told from a more humorous angle.
I'd appreciate any suggestions. Thanks.

Thanks for all of the great advice guys. It's helping.
After that opening, we go back to the day she gets the picture and the picture gets described at that time. I guess that is why I didn't elude to what the picture was in that line. I'm going to come up with a one word description that descibes what the picture means to her, such as eye-opening picture, etc...
I've had it worded that way before but keep changing it.
I've only changed the opening few lines 50+ times and I can't say they've gotten better. Good thing I joined AW. I'm going to get that opening line the way I want it once and for all.
Thanks again guys and keep those suggestions coming.

"Until the day I got the eye-opening picture, I couldn’t have come up with one thing I'd change about my life. Not my career. Not my boyfriend. And, most important, not one single thing about myself.
I was happy. Confident. Secure. And, for that brief moment in time, I felt like my life was, finally, moving on a fast track towards perfection.
Of course, it didn’t last. Once I had the blasted picture in my hand and seared into my brain, all of my good feelings came to a screeching halt. The fast track became the tangled track and perfection became chaos and confusion, suspicion and doubt. "
And here I go into the day it all started...

How about this? Any better?
I liked "Impossible to come up with" but my character isn't that secure. Way more secure then she used to be, but, she still has enough doubt to not make that strong of a statement.
I also added "finally" to the headed toward perfection as she hasn't felt that great all of her life.

Thank you guys for all of the help. I've been tinkering with it and will let it rest for a few days before I go back at it.
I'm overwhelmed by the gracious help I've been given here. WHat a great group of people.
