"For everything you have missed, you have gained something else; and for everything you gain, you lose something else." - Ralph Waldo Emerson
""The whole of what we know is a system of compensations. Every defect in one manner is made up in another. Every suffering is rewarded; every sacrifice is made up; every debt is paid." - Ralph Waldo Emerson
These two quotes really give you something to think about... When you think you have "failed", what you have you really gained, learned?
When you have "succeeded", was there something else you lost, such as a lesson of some sort... an epiphany of gratitude for something else?
