Indeed, having a look at it, Every big thing in our world simply started as an idea on someone's mind.
The impact realized once an idea is put down to action is enormous and even the original bearer of the idea can hardly comprehend.
I encourage us all to pick up the courage, kick off the fear and get our ideas down to action. Someone somewhere is not thinking about that thing...that you are thinking of..where as they need it so badly.
Do you have a start yet?
OK, you've got to start NOW!!!
