Time is fluid. I often had many projects to work on for a week, and I had to figure out when I would do them, and fit this around constants. I have a painting due in a week and I'm not doing anything Monday night so I can get it done then but the homework for Wednesday needs to get done Tuesday morning so that I have time Tuesday evening to do Friday's homework. After weeks and weeks of thinking like this, I don't think in any other way.
High school did not prepare me for this time scheduling because if we had homework, it was probably due the next day. I think this forces procrastination. I think this evolution of thinking about time happened when I realized that if I get something done sooner, I don't worry about it.
I realized that as much as I dreaded my drawing class, Professor taught us how to think about the process of the drawing. It wasn't about pencil control or shapes, but about how to see the human figure from the inside out. We break down the human figure into the gesture and then simple shapes.
I learned:
How different kinds of light create color,
how to mix acrylic and oil paint,
how to create any color with the primary colors and white,
how to see color and shadow,
how to make a design interesting,
how to paint from a still life,
how to arrange a still life,
how to use InDesign, Illustrator, FinalCutPro,
how to generally use a Mac
how to mount anything on nice paper,
how to conceptualize a plan into a 3-dimentional shape,
how to cut and rip paper in a straight line,
how to quickly pack,
a decent amount of pre-1800s art history
and I don't know what else. There's a lot that's not in there.
