For me, a risk is jumping into something that has unknown results. Most people would identify a risk as something that may have dire consequences if success is not reached. It depends on how you define success.
I take risks everyday. Most are insignificant. However, the more risks that I take on a grander scale, the more quickly I am able to move beyond the idea of a risk and how it can hold me back. I can be more prepared and focus on success.
Failure is a strong word. Again, it depends on how you define success and I don’t define failure the same way I think others do.
Failure is the opportunity to do better the next time. And the next.
