1. 若不给自己设限,则人生中就没有限制你发挥的藩篱。2. 若不是心宽似海,哪有人生风平浪静。在纷杂的尘世里,为自己留下一片纯静的心灵空间,不管是潮起潮落,也不管是阴晴圆缺,你都可以免去浮躁,义无反顾,勇往直前,轻松自如地走好人生路上的每一步3. 花一些时间,总会看清一些事。用一些事情,总会看清一些人。有时候觉得自己像个神经病。既纠结了自己,又打扰了别人。努力过后,才知道许多事情,坚持坚持,就过来了。4. 岁月是无情的,假如你丢给它的是一片空白,它还给你的也是一片空白。岁月是有情的,假如你奉献给她的是一些色彩,它奉献给你的也是一些色彩。你必须努力,当有一天蓦然回首时,你的回忆里才会多一些色彩斑斓,少一些苍白无力。只有你自己才能把岁月描画成一幅难以忘怀的人生画卷。
