next Rtm's advice hadn' included anything that. I wanted to do something completely different, so I decided I'd paint. I wanted to how good I could get if I focused on it. the day after stopped on YC, I painting. I was rusty and it took a while to get back into shape, but it was at least completely engaging.1]  I wanted to back RISD, was now broke and RISD was very expensive so decided job for a year and return RISD the fall. I got one at Interleaf, which made software for creating documents. You like Microsoft Word? Exactly That was I low end software tends to high. Interleaf still had a few years to live yet. [] the Accademia wasn't, and my money was running out, end year back to thelot the color class I tookD, but otherwise I was basically myself to do that for in993 I dropped I aroundidence bit then my friend Par did me a big A rent-partment building New York. Did I want it Itt more my place, and York be where the artists. wanted [For when you that ofs you big painting of this type hanging in the apartment of a hedge fund manager, you know he paid millions of dollars for it. That's not always why artists have a signature style, but it's usually why buyers pay a lot for such work. [6]  Original Tokens: 10719 Compressed Tokens: 308 Comressed Ratio: 34.80x
