I don't know, doesn't the outcome matter? Trying is admirable, but if a person tries and fails and I never try; at the end of the day we're both in the same place, no?
What a bizarre statement. This is a generalisation that can easily be shown to be false. If I try and win Gold at the olympics, but fail (only winning silver), I am in a completely different place from you who never tried. There's a million other counter examples.
I think it depends on how you fail though. If you learn something from the experience, your odds of succeeding on the next try increase. Many goals are achieved through a succession of failures.
If you're genetically gifted with a talent and genetically driven to "train" you'll be much better off than someone with only one trait.
