Failing is the best opportunity to learn because reality show us we did something wrong, so it’s up to us to fix our mistakes, or keep making them.
It’s also good for our personal balance, because failing teaches us we aren’t perfect, and realizing that can be very humbling from time to time.
Life is about learning, and acomplishing our goals, but we need to have a lot of strength to do that, and having failures ultimately makes us stronger in the long run.
