FAILURE IS A GOOD IDEA

Rock bottom became the solid foundation on which I rebuilt my life.
Some failure in life is inevitable. It is impossible to live without
failing at something.
Failure gave me an inner security that I had never attained by passing
examinations. Failure taught me things about myself that I could have
learned no other way. I discovered that I had a strong will, and more
discipline than I had suspected; I also found out that I had friends
whose value was truly above the price of rubies.
The knowledge that you have emerged wiser and stronger from setbacks
means that you are, ever after, secure in your ability to survive. You
will never truly know yourself, or the strength of your relationships,
until both have been tested by adversity. Such knowledge is a true
gift, for all that it is painfully won, and it has been worth more
than any qualification I ever earned.
