In order to get good ideas, entrepreneurs need to spend time by themselves. To get good ideas, being focused without being disturbed is the key to success.

Most innovations are re-combinations: applying a principle or a concept from one industry, market or technology, and applying to another.

Entrepreneurial ideas project a potential future, an option that could be turned into reality. But in order for that to happen, only execution and learning can tell whether the option can also be a reality.  

The origin of many entrepreneurial ideas is experience: deeply knowing an industry, customer problems, supplier problems helps you to identify unaddressed needs, or to have seen options tried and failed before.
