Risk-taker

Definitions: (1) one willing to expose themselves to danger, ranging from minor challenge to major peril; promethean <especially creative, courageous, and innovative>; (2) venturesome

Quote: The challenge is that the day before something is truly a breakthrough, it’s a crazy idea. And crazy ideas are very risky to attempt. — Peter H. Diamandis (1961-) American engineer & entrepreneur

Comment: For a little kid wanting to ride a bike is worth the risk of scraped knees. But they don’t anticipate the pain, only the freedom. However, very few go on to conquer the unicycle.

Observation: The first circle is your comfort zone. Risk taking is lived in the second circle. And it is really risky if you get out to the third. Of course, these ‘circles of risk’ are relative to the individual.
