Every single thing that ever changed the world was once an inkling of an idea in the back of someone’s head. Facebook, Twitter and Google were once ideas that came out of dorm rooms and garages. Companies like SpaceX which has privatised space, Planetary Resources which is planning on mining asteroids and Tesla with their gorgeous electric cars were once similar to the crazy ideas that you have. But Ideas themselves do not change the world; you have to breathe life into them.
“A man may die, Nations may rise and fall, but an Idea lives on” – John F Kennedy
An Idea which is not put to good use is nothing but a useless fleeting thought and sooner or later somebody else will come up with it. So, take a stand, make your idea work, and bring it to life. With the advent of internet and social networking, things that only Governments were capable of, is now under grasping distance of a few highly motivated individuals.
