Ideas are cheap because you can have them lounging your chair doing nothing but thinking. No risk-taking involved. No years of hard work involved.<p>The reason Silicon Valley (rightfully) values execution so much more than ideas is because it takes guts (putting in own or other people&#x27;s money) and sweat (hard work, focus, attention to detail) and a whole lot of other things to take an idea to product on the street. This is why most ideas never make it to product.<p>So compared to ideas, sweat and guts are quite rare, making ideas the cheap good. Easy as that.
