Ideas we have been told, rule the world. Some ideas could start as being ridiculous or laughable, and then they become global success stories. Like electricity, like rail travel, like air travel, and Facebook, and Twitter, they all started as abstract ideas in the heads of some folks with unusual thoughts. Sometimes, I would marvel at the 21st century leaps of technology and would wonder how we had been able to fare for so long without them. Ideas come as answers to questions raised with the intention of solving problems.
