Flash programming

Hi /prog/,

So basically I have a lot of spare time on my hands right now, and I feel I might as well use it to learn something.

I want to learn flash-programming, for a start. Anyone can recommend me any place to start, which program to use, and websites/books with decent advice?

tl;dr: Advice on starting to learn flash.

Alternatively, if you're a beginner and just want to write your first flash game in an afternoon, try something like this tutorial for a space shooter: http://www.kongregate.com/labs
