"Programming is a left-brain endeavor, designing utilizes the right side of the brain."<p>Sorry, that's a myth. Both engage both sides of the brain. Most of what we do involves both sides of the brain. There are plenty of books around busting the myth that 'some people are left brain and some people are right brained'. Programming involves much of what is associated with 'right brain thinking': leaps of intuition, random thoughts, synthesis, looking at the bigger picture. While 'designing' (by which I take you to mean 'aesthetic design'?) involves much of what is associated with 'left brain thinking': analytical, objective, rational, logic.<p>What many folk do not realise is that 'design' is mostly something technical that can be learned. It's a set of rules, guidelines, processes and techniques that can be taught and practised. It's not some magical, right-brain, talent you're born with, it is something that is learned, practised and honed.<p>Sass is, in my experience, no harder to learn than HTML or CSS. Much easier, in fact if you already know CSS. It's nowhere near as complex as, say, Javascript or PHP, which most web designers seem to be able to handle to some degree. If a web designer (as in someone who specialises in HTML, CSS, graphic design, typography, IA) finds it too hard or complex, they either need to practice more, or find another career, because they're going to be redundant pretty soon as CSS and HTML get more complex with the transition to HTML5 and CSS3.
