In life, we experiment many times, some times we win and many times we fail. But in spite of our failure we have to keep experimenting in life, as this is the way to go, and the more experiments we do the better we get at handling failure in life.
Success is gold in the coal of failure, we have to search for gold of success in the mine of coal called failure.
As it is rightly said, all life is an experiment, the more we do the better we become.
Wish you a happy life!!
