I think that some of the most valuable lessons we learn in life come in regards to our failures. There have been countless times in my life where I think, "Boy I wish I had never said that." or "I should have done something different then." There's not a whole lot of times where you succeed in doing something and learn a valuable life lesson, though those times do exist, they are slim in comparison to the times of our failures. But in order to grow as an individual we need those failures, we need those hard times we can't possibly get thru alone. So take a step back sometime and look at yourself and think, "what did I do to become the person I am today?" What were the failures in your life that made you a better person? A stronger person? A different person? And as self aware and individualized as you are now, you can only imagine what failures lie ahead that will help you evolve even more. Our lives are a never ending chain of events that are constantly defining and redefining who we all are!
