Flash is the reason why I'm a programmer today. It was Flash which kindled my interest in computers and made sure I spent hours playing around with it and then other aspects of computers. That era of discovery and expression was something special.
I had a similar experience. I learned ActionScript pretty early on (around age age 16 or so) because it was easier to get something visual built than any other thing I had used, while still feeling like "real" programming. AS3 is actually quite a pleasant language to work in, and while I'm glad that I don't need to muck with Flash plugins anymore, I do miss how easy it was to get something built when I was just bored…
Also, it was really easy to reverse engineer a flash file. One could just import the .fla file into flash and see a lot of stuff that was going behind the scene - assets and action scripts were easily available to explore. This was my favourite way to get better at flash; I would go to templatemonster.com and browse through all the cool flash websites they had, then navigate to the temp folder of IE and then copy paste all the .fla files into my own personal folder for later dissection.
