Have you ever felt like you could really use something that just doesn't yet exist? That kind of thinking (and plenty of accidental brushes with luck) has lead to many of history's greatest inventions. Most of the world's most monumental inventions arose out of a simple, everyday situation, a bit of brainstorming, and a lot of experimental failures.
Today's inventions inventions range from those shown on late-night infomercials to those in Silicon Valley tech startups. (Yet even modern creators would be hard-pressed to do much inventing without a lightbulb to work under.) Learn the stories of history's most significant innovators, and take notes. Lots of notes.
