Meditation 8.32-33

32. You must plan your life, one action at a time, and be content if each acquires its own end as best it can; and that it should acquire its end, no one at all can prevent you. 'But some external obstacle will be in the way.' None to prevent action with justice, temperance, and due reflection. 'But possibly some other activity will be hindered.' Still, by meeting the actual obstacle with resignation and good-temperedly altering your course to what is granted you, a new action is at once substituted, which will fit into the plan of which we are speaking.

33. Accept without pride, relinquish without a struggle.
