I’m not able to AP myself, but simply because I’m not determined to learn it.
I’m already filled up with stuff to test and learn, and I think that it’s okay to learn AP when I get older and get a job where I don’t have to worry about sleeping late (I prefer using rythm-napping + rope-tech I am to try it out).
But I simply won’t even try now.
Not that I can’t help though. Here are some truly great links:
