Nothing can stop an idea whose time has come - Famous Positive and Inspiring quote

An oft-quoted famous positive quote, it's an inspiring quote. It just implores anyone with an idea to Just Do It. Do not hesitate, dilly dally or be in doubt when you have hit upon an idea. Gather the guts to overcome initial hesitations and criticisms from those around you, and launch the idea. Christopher Columbus did that. So did Google's founders.
If they can, so can you! Be Positive.
