I was really happy to see this post. As a DBA I live in constant fear that I'm going to get the call that a mission critical application is down due to a DB being off-line. Seeing this post confirms that I'm not alone. Two important points that I feel are really important:

1.Challenge your negative thinking

2.Practice

Sometimes the highest expectations we put on ourselves. There is nothing wrong with high expectations; just make sure they are possible (and realistic).

Thanks Stanley!
