Many times these great ideas are born from the frustration of everyday life, mixed with a bit of experience and education. The result ranges from very simple solutions to much more complex solutions depending on the background of the inventor.
In this video is an example of a great solution turned unto a great product developed by someone who obviously had a significant background and education in chemistry.
Don't get frustrated when you see these complex products being developed and compare them to your more simplistic efforts. You are the norm, not them, and while your contribution may not be the chemistry behind this hydrophobic concoction - it very well could be an application for it that only you envision.
