I am a father of a four year old boy (and a one year old daughter). My biggest fear for him is that he will not become successful.
Not in the sense of how society has coined the word, but in the sense of being a human being. Living a happy, joyful and healthy life.
My fear is that I am not paving a path or laying a foundation for him to live and be his authentic self, regardless of his surroundings. This, for me, is the definition of success. To be human, how we were intended to be.
