Can Curiosity & Maturity Coexist?

It is hard to put a price on what we gain from experience but for some of us there is one great quality that gets expended in this evolutionary step, curiosity. The ironic thing is that curiosity is mandatory for discovery, success & experience and we kill it in the first place as we grow up, by manifesting ego. The first point where loss of curious outlook occurs is when we start to think 'I know', whereas, to start to know something, we should avoid thinking just that.
For those of us who put ego before experience & get hurt & fatigued with every endeavor they make, what is needed to be remembered is that every event in life is a trial. We live to experiment. If we lose the agility to experiment, our life will only be a emotionless chase to nowhere except collecting a few ideas that support our ego.
A childlike curiosity is nature's primary & most precious gift. It is like water to a tree, necessary at the very root & at every step of its growth to gain height & strength that this world demands. All that is needed is to let the water of curiosity be present in the soil of life, to moisten & tender every mature flower.
