planar analysis

This is difficult for me, I understand it when I see images of it, but when I actually try to figure it out, I have problems. I'm not sure why it's so hard for me to think of, I guess I have a lot of difficulty converting 2-d images to 3-d, but that's what art is . . . really I should just practice it and stop complaining about how bad I am, but complaining is so much easier! Well, I will practice. I bought my paper and bigger drawing board, so now I just need to plan out where and how I will do my next homework assignment. Apparently I will be doing it all tonight, since I will have 0 free-time this weekend . . . work sucks
