人生不可以复制、粘贴，即便是设计好，也未必按设计的方向走去。谨以此书献给所有心怀理想以及正在为之努力奋斗的青年们。有一部苏联的励志小说《钢铁是怎样炼成的》，书中有这样一段名言：人最宝贵的东西是生命，生命属于人只有一次，一个人的一生应该是这样度过的：当他回首往事的时候，他不会因为虚度年华而悔恨，也不会因为碌碌无为而羞耻；这样，在临死的时候，他就能够说："我的整个生命和全部精力，都已经献给世界上最壮丽的事业—为人类的解放而斗争。"(Life cannot be copied and pasted. Well-designed as a life may be, it may not develop as the plan.It's dedicated to the young who have dreams and are striving for them.The following saying is quoted from the Soviet inspiring novel How the Steel was Tempered:"Man's dearest possession is life. It is given to him but once, and he must live it so as tofeel no torturing regrets for wasted years, never know the burning shame of a mean and petty past; so live that, dying, he might say:'All my life, all my strength were given to the finest cause in all the world-the fight for the Liberation of Mankind'".)
