I have never met, seen or heard a person who as never failed. Because people fail in so many things. Marriage, business, competition, studies etc.
With this in mind I see no need for anyone to fear to fail. Failure does not define us only what we do after failing defines us. So when you fail just accept that you failed, do not sugar coat it, then move on with your mission.
There's no life or mission as been accomplished in a straight line. When you let failure define you it means your lied to yourself that you're not human, but divine. Because divine beings do not fail only human fail.
Remember this also;
Real life is not Instagram, where the best shot, is edited and posted. The ugly is kept away from your sight. Real life is full of failures.
I close my comment with this quote from Dr Maxwell, he said sometimes we win, sometimes we learn.
