Haha, it's okay. I just started origami about 5 months ago. I used to do really simple origami when I was little, so picking it up was not that hard for me. The key is to be very precise at every step, and look at the following step's picture for reference, because mistakes tend to amplify themselves when you get to step 60 and above.

And yes paper was really a problem when I got to the more complex models. Those packs of origami paper sold in my general art stores are good for intermediate models, but for complex, they tend to rip and tear.

For models like Kamiya's dragons you need REALLY BIG paper. My personal choice is parchment/tracing paper. They're really strong and thin, but it takes some getting used to. They also come in very large rolls like 60 cm widths, and they're relatively cheap compared to specialty papers like Thai Unryu.

I hope this helps in getting you started! Sorry for the long message; it's even longer than yours.
