The theme thus, for newbies at least, is just to get started. As my friend Jim Milles says, “anything worth doing is worth doing badly.” People (such as myself) get too hung up on preparing to do things right, to get things perfect. Being perfectionistic can really prevent you from getting started. Just jump in, whether it is audio or video, and get recording! Get a microphone, Audacity software, and start audio recording! Or take your digital camera and start recording video. You can build the technology you are using as you go further along.
So, as the shoe people say “Just do it!”.
