Well, if you can't see the small parts, work from top down first. I've often coded things as:
my $data = get_data(); process_data($data); print_result();
literally, as if it were pseudo code. Then I write stub routines, like:
sub get_data { # returns scalar data pointer to my structure my $return_value; my $db = open_database($credentials); # must declare this above my $data = query_db($db, "select * from bar"); $return_value = massage_data($data); return $return_value; } sub open_database { my $cred = shift; warn "open_database doing nothing"; return undef; } ...
and so on... Then at any time, I can "run" what I've got. And stay focussed on each area of development. If I need a class, I'll develop a generic class that I can plug in.

Again, the goal is to type a dozen-ish lines of code, then invoke it. That's nearly always been possible.
