There are thousands of them swimming a race. Only one gets to the goal first. It is a race of life; it has only one winner. that victor is your son.
From the earliest, he was like you but unlike you. After all, he came into a world far different from you. He didn't ask to be born. In fact, he didn't ask for any of this. he just was and is. In many ways, it is a miracle that he is here.
A son is a gift not to be taken lightly. You are an honored guest as he progresses through his early years. You may be the one to hear him say his first word, open his first door, say his first sentence and give you a hug for the first time. He will amaze, startle, anger, impress and reject you all in the same day. He will be a pleasure and an enigma for all the time that you know him: for his world is not your world; his thoughts are not your thoughts.
Nevertheless, you will be in agreement with him on many things; oppose other patterns. As a father, you should be more of a catalyst than a director, more of a mentor than a commander... more of a supporter than a pusher. It will be hard for you at times. It it certainly will be difficult for him at times, also.
What you want for your son may not be what your son wants for himself. You can push and make your son a mediocre doctor or lawyer. At the same time, you can rob the world of a great artist or writer. Your son should be able to live his life and not replicate your profession unless he is motivated to do so.
