Whatever happens, take it as a matter of course. You are not running the world, nor born to set it right. You are not half so much the master of your own actions as you think you are.
Deal justly by yourself. Few do. They regret making that decision, or performing the other action, or neglecting such or such an opportunity. They reproach themselves for their hastiness or carelessness.
What folly! far worse results might have attended a different course. We can see but a very little way in life, and that very darkly. We can neither forecast events, nor predict our own decisions in new circumstances.
If we act at the time with reasonable prudence, we need never waste later moments in self-reproach. Any other decision than the one we adopted would likely enough have brought still more dismal consequences.
Remember that you are never deserted by all until you have deserted yourself.
Do not confound a decision with its results. The former may have been at the time the wisest possible, although the latter were disastrous.
