I don't think you can ever do your best. Doing your best is a process of trying to do your best.
The function of mental processes is to mediate between the needs of the organism and the demands of the environment.
Truth is like a blanket that always leaves your feet cold. You push it, stretch it, it'll never be enough. You kick at it, beat it, it'll never cover any of us. From the moment we enter crying to the moment we leave dying, it will just cover your face as you wail and cry and scream。
我是帝国在颓废的尽头。
我们不是从祖先那里继承了地球；我们是从子孙那里借来的。这个真理指导着我们做出的每一个决定。
