I wonder whether she has done truly awesome things with her life. One of these pieces of advice you hear often regarding your true vocation goes something like _what would you do if you had no fear?_.

Well, she literally hasn't. So is she an Olympic champion who fights crime during the night and writes amazing novels during the day and commutes to work swimming together with a school of piranhas, or has she led a relatively normal life? She can follow her passion with no fear of failure or success or whatever!

I'm genuinely curious to find scientific evidence about whether fear is the only thing holding us back or there are other factors.
