Luck
Luck is not predicted consequence happened in a time and has the positive reaction. Decisions from the outside not connected to each and not awareness of their existing. When somebody says that is luck, he took that from you, your goal and your achievement . Your feeling of yours, whatever that is. The control of your conquest. Every effort after that comment, that that was luck, is useless. Unnecessary and irreversible, degrading openly. Which is the important reason of that same luck, because it doesn't mean anything. It is not wright and it is not wrong. It doesn't do anything.
