The quote wasn't meant to manipulate or make anyone feel bad. I just posted on it cause I know how amazing it was for to to say, "wow, yeah there is something else I want to be doing and I am letting my fear stop me." Writing is not the only thing that many of us dream of doing. It isn't even the biggest thing that some of us dream of doing. But whatever the dreams, fear of failure is a massive stumbling block.
And I think you can say that you have not failed in something if you view success as the ATTEMPT, the brave choice to chase the dream in the first place. At least you can say you tried. At least that will be one less, "What if?" question that you have to live with. I think that spells success.
