The life of an inventor is not an easy one. First you have to come up with a good idea that solves a problem in a way that no one has thought of before, and then you need to design and engineer your idea to take it from theory to reality. The very nature of invention means that inventors are continuously pushing the boundaries of what’s possible. This drive to discover the next Big Thing has been a boon to humanity and has given us inventions like the steam engine, the automobile and the personal computer. It's the major reason why we're still not huddled in caves fighting off wolves and cowering at the crack of thunder.
