Moreover there is large evidence that Art (and humanities) can set you in the mindset of hacking. PG himself says that painting can teach many things about hacking [1] and I am living proof that Art can definitively teach you how to hack (and also be an entrepreneur): I received my first computer only when I was 19, but I had been hacking since I was 3 years old, through the art of Berrocal whose sculptures can be taken apart, transformed and combined, they are like 3d puzzles, tactile problems that need to be solved [2]. It has taught me practical tools, methodologies and ways of creatively find solutions that can be applied to both programming and to the day to day challenges of entrepreneurship.
There is actually a necessity and a current trend to connect Arts+Design+Humanities in the STEM education. it's called "from STEM to STEAM" [3] and it's backed by great figures in both art and computer science such as John Maeda
Don't despise arts+humanities, you'll be only limiting yourself. A good old poem can hack your brain! give it root! ;)
