Failure is simply a part of life.
Most of us failed when we first tried to walk, first tried to talk, first tried to read, first tried to ride a bike, first tried to...
In most things that are not simplistic, we fail repeatedly on our way to mastery.
Failure is a powerful learning tool that pushes us forward, toward heightened effort, toward improved skills, toward keener insight.
All those thoughts about failure hold true UNLESS our failure springs from lack of authentic effort, from peon levels of commitment, from purposeful attempts to derail. In those cases, our failure diminishes us and makes us weaker. It is, in effect, failing backward.
Failing forward is far nobler than that, and it is most often experienced when we're chasing worthy dreams.
