For searching for my new book "Earning Serendipity" I came across a great little text called 'Entrepreneurs ToolKit' published by the Harvard Business School. You might expect the expensive time discussing what means to be an entrepreneur and they gave a definition that I like a lot. It is this. The entrepreneur puts skin in the game. I think that almost near said. The entrepreneur is the one that puts skin in the game. This can be your money, this can be your time, this can be your passion. To be entrepreneurial means you have a vested interest in pursuing at end results.
