Since we don't manufacture much in the US anymore it's becoming unpatriotic to not worship intellectual "property." It's almost all we've got. But still, some very successful people have chimed in to the contrary:

Napolean Hill (Think and Grow Rich): Ideas without action are impotent

Thomas Edison: Genius is one percent inspiration, ninety-nine percent perspiration (he became a litigious bastard anyway)

If you're in business to make money, almost without exception it's going to be all about making and keeping people happy. That takes ongoing work, it only starts with an idea.
