1. get
text editor (textmate if you are on os x, vim if you are on windows)
2. pick up a dead tree book on programming on a programming language you think you'll like. There's more commitment if you actually buy a book
ruby => 'the ruby way' (the book that finally made ruby click for me -- I cannot recommend it enough)
perl => 'programming perl' (my first love affair with a language, I love perl)
scheme/lisp => SICP (too expensive to buy on a budget though)
3. you must have a project you really want to do in code. Without a real program to write, you have no path through the library of form, because the possibilities are endless :)
