Life is like photography, we use the negatives to develop
"No one is perfect" is an old quote to show how humans are inevitable to make mistakes. Each day of our lives, we live to learn, unlearn, and relearn and wise men would say learning never ends. Looking back to all the years we've lived, we'll realize that we have made more mistakes than we've done something right but each mistake we make is what helps us develop ourselves toward the future we envisioned. If we could see life in such lenses, then we could equate life to be like a photograph.
Our nature wires us to live as if perfect, we hate to feel the sting of rejection, and thou becomes bitter over each negative outcome, when in essence we can't be great without passing through years of learning which comes through our period of failing and picking ourselves up to try again. The only person who has never failed is he who has never tried. It hurts to fail, it makes us feel like failures at some points, and sometimes it's hard to bear the mockery and ridicule but life has been designed in such a way where the negatives are what we use to develop.
I have tried to observe life as a photograph, we make of it what we want. We can add more brightness to it or dim it to the level of light we want. The beauty at the end depends on two things: how well we've learned to manage the exposure, settings, etc. From critics and our level of professionalism from days, weeks, months, and years of learning. So how we see negatives in our life matters, do we see failure and negative responses as a ladder to the top? Or as an agent that shows our weaknesses in the open. How we manage our negative outcomes matters in the long run. Life is anything your mind allows to dominate it.
