求翻译：这就使我感到，我几乎什么都不知道，也不敢说我能做什么事情。我在事前和开始做某事之后都看不清自己的能力，只有在自己做完之后才能看的清楚：我对自己力量的了解，就像对初次遇到的人的力量的了解一样。因此，我万一能胜任某件事情，就把它归功于自己的运气，而不是归功于自己的能力。是什么意思？

It makes me feel, I almost don't know anything, did not dare to say what I can do things. Both beforehand and I start to do something after not read their abilities, only after they finished to see clear: my own understanding of the forces, as understanding as to who first met the power of. Therefore, my case can take something, they owe it to their luck, rather than due to their abilities.
