One source of business ideas

One source of business ideas is with people who already own and manage companies or who work for companies.

Through existing work, an idea crops up.

Quite often the idea is outside the company's core business.

People who have these ideas and want to develop them should be encourage to talk to others about developing them and starting their own companies.

Of course, any non-competition and propietary issues (if any) should be taken into consideration in advance of taking the plunge.
