I used to take a lot of pride in saying, "I don't learn anything if I don't learn it the hard way." (Or some variation thereof)
In reality, this isn't the best way to exist. It certainly isn't something to be proud of. If fourteen people in a row jump off a cliff to their death, why do I, the fifteenth, think I can fly? If a restaurant tells me "careful, the plate is hot," why do I touch it? They tell you it's hot becuase someone burned their hand very badly, then sued them. Do I think my skin functions differently? Why do I feel the need to see for myself in everything.
I had a company before All My Affairs. I was given the advice from a person whose opinion I value greatly. He said, "Be careful with loss leaders, most of the time their just lost. In fact, I'd just avoid them completely." I did not - to my peril. I was also told, "Build slowly, we tried to grow too fast, and it ruined us." Again, I did not learn from the mistakes of others.
The old adage says, "A smart man learns from his mistakes. A wise man learns from the mistakes of others." There is a book called The Spirituality of Imperfection. If I may crudely synthesize it into one sentence, it is: Embrace and build upon mistakes, becuase failure to do so is an attempt to play God.
Humanity - you and I - are imperfect beings. It is embedded in our DNA at a deeper level than the color of our eyes.
Written on the spine of my most referenced book are the words Remain Teachable. I must learn from my mistakes to grow. I must learn from the mistakes of others to grow exponentially.
