I have come up with a life philosophy called "Guaranteed Success". It equalizes failure and success into the same equation: Learning. Whether an intended level of success is reached or not is no longer the motivating factor in "trying" as you've mentioned in your article.
So many shy away from "getting in the game" because they only see their success/failure and not through to the end which is the collection of the experience, whether its failure or success. True success is in the collection of an experience, good, bad, or indifferent.
The regret that comes from inaction is truly permanent, but so are the lessons of success and failure. Some of my most valuable lessons came as a result of not achieving my intended level of success. I did benefit, however, from the failure by learning more about myself.
This is the ultimate reward; to know more about oneself.
So, in all due deference to your post, whether one tries and fails/succeeds or doesn't try at all, the experience will result in self-gnosis. The quality of the experience is determined by each individual, good or bad, success or failure, regret or reward; "It's all learnin' baby!"~Said in American Southern Accent

We are all "Guaranteed Success" if we detach from the specific desired outcome and reattach to the living experience, whatever it is.
