时间如梭，白驹过隙，2015年还没有来及回顾，2016年脚步马上就要悄悄来临，转眼间本科毕业已有10年了，子曰：“吾十有五而志于学，三十而立，四十而不惑”。目前三十多也没有立，更谈不上不惑了，更多是面对现实一种的诚惶感。值次之际，来纪念即将逝去的2015。
六年前南下广州工作，而后辞职，东渡扶桑岛国继续深造，拿到日本国费文部省的奖学金，一年的研究生加上三年博士生活，今年博士毕业，一路走来，感觉这四年多的国外生活使我有点温水煮青蛙的感觉，有点不思进取。今年4月回深圳参加国际人材交流，9月回成都参加专业培训，12月份回广州参加海外科技人材交流，感觉国内的形势变化很快，以前广州的同事大多开了小公司，虽然有规模不大，但都还不错，非常替他们开心。反观自己，大好的青春时光都耗在求学的道路上，求学数十载，虽然有几篇科研小文章，然而却没有太多的成就感。但是毕竟，在这几年的求学生涯中，还是有不少的收获，博士研究过程中也是一个不断自我救赎的过程，在痛苦的过程中，不断调整自己的心态，不断的学习，才是这个过程的磨砺我人生的财富，让我不断的做加减法，不断的自己打气，不断的反思，让我尽量平衡的面对生活中的每一天。
非常感谢东大这个平台，使我明白做科研的基本独立素质，从选题，到数据搜集，处理与分析，解释科学背后的诱发原因等等。非常感谢我的导师小口高 (Prof. Oguchi Takashi) 老师，他经常教诲我们：我要让你做一个科学家，而不是一个技工。他的严格要求让我明白，科学与技工不同层次的要求。要感谢的人太多了，感谢所有给我帮助的人。
现在虽然是空间情报中心做着研究员的工作，但是面对现实，尤其成家以后，担当的责任更多了，虽然自己也有点喜欢科研，然而，科研需要付出的太多，博士这几年，由于经常在实验室呆的比较晚，忽略了家庭，冷落了家人，继续做博士后领着微薄的工资，面对未知，还是进日企拿着不错的薪水，过着小康生活，向左向右的选择，毕竟，科研有时不能当饭吃，虽然有时对科研有太多的不舍，尤其面对成家时候，用钱的地方太多，在这新年之际，还是好好思考下自己的人生未来。
谁言寸草心，报得三春晖！在这里特别感谢我的家人，尤其是我的父母，他们还不停的支持我，关心我，鼓励我。经常问我“缺钱吗？家人替我承受了生活的艰辛，从而使我可以专注于自己的学业研究，亏欠他们的实在的太多。
人生新的一篇已翻起，但愿我们的明天更好……
祝大家2016新年快乐。
附带上我的博士论文中的英语致谢，望见谅。
