Interesting about private collector/gallery symbiosis.
On drawing.. don't think you should give up so soon. Van Gogh starting out was an awful drawer.. it took him many years to get to his masterpieces (10000 hours??). You should pick up "Drawing on the Right Side of the Brain".. it's a classic in that it consistently gets people to a respectable skill level in about 40 hours of work. As the title states.. it can help release your creativity and perception too. You really start to appreciate pieces in museums when you truly understand how difficult some of the techniques they use are. I used to just walk by graphite/chalk sketches without batting an eye.. now they're my favorite.. and can spend half an hour looking at one sketch. I can't even begin to appreciate the color wheel yet.
