How to learn to program?

How did you learn?  I'm not asking how you learned a particular language, but how you learned how to program in general.

Last I checked Larry Wall didn't care (though that changes every 2 years I estimate... he's still into chartreuse though), but I can't help but notice that a Perl REPL would be perl (or perl-repl, or perlrepl, or more likely something stupid like replerl) but not "Perl".
