I like these answers so far. I think the most important skill in martial arts is...
... The skill of discernment.
With discernment you will appreciate from the beginning what is the right and wrong art for you, the right and wrong teacher for you and the right and wrong way for you to train.
Discernment will allow you to view your weakness without the fear that causes denial of that weakness. With discernment you can work your weakness to become better. Or the best. Of course, discernment will show to you that even if you are the best you can still be beat. Then again, it is discernment that will persuade you that even if you cannot be the best, or are no longer the best, you can still be the best that you are.
The easy question to answer is what is the most important skill. I think the more difficult question to address is one that asks about acquisition of that skill.
