It is true, unless you personally try out something, you will not know the effect. It need not necessarily a mistake. It can be anything in life you can try, win or fail. You will know the after effect only when you personally experience it. A flower is there for to enjoy it's fragrance, not to be totally squeezed. Life is there to be experimented to know good, bad and ugly. You can draw your inference from your personal experiences to become matured to deal with life as it comes. thanks for sharing
