How would you behave if you knew you could not fail? How would life be different? What would you change and what would you immediately stop doing? I think when you live into that question you will discover the adventurer in you, the risk taker. We only show up authentically when we are in a space of discomfort; we come alive in a whole new way and our genius comes out. We find inner resources we didn't know we had and we perform in ways that often excite and astonish.
Occupying this "could not fail" space invites our dreams and our aliveness: write that book, take voice lessons, quit that mausoleum of a job, tell that person they are hurting you, go skydiving! Do it all. At the end of the day, all we will have is our experiences. Your real job is to build and collect those dream experiences now.
