I had rather attempt something great and fail, than to attempt nothing at all and succeed

I'd rather attempt to do something great and fail than to attempt to do nothing and succeed.

What great thing would you attempt if you knew you could not fail?

Most people who succeed in the face of seemingly impossible conditions are people who simply don't know how to quit.

What would you attempt to do if you knew you would not fail?

If you listen to your fears, you will die never knowing what a great person you might have been.
