Failing at something is one of the most effective ways for humans to learn, grow and achieve success.
It is when we learn from ours and others mistakes that we can achieve higher levels of intellect to determine how to be smarter, more kind, make better decisions, be better at our jobs etc for the next time...
Look at history to see how good things have come from massive failures.
We can't escape failure in life and we cannot always control the consequences or fallout from our decisions/actions, but we can keep trying. That is what the above quote is all about.
What's wrong with this quote? Trying at something and failing is better than never trying at all.
