I don't think I was a clear in my editorial as I should have been. In regards to the job, I was specifically referring to those DBAs who adamantly follow the rule of "if it ain't broken, don't fix it" attitude. As I said in my editorial, I think it is "important for DBAs to consider any new technological options carefully, and then take measured, controlled risks, in proportion to the perceived benefit." Any change is a risk, but it can be a controlled risk.
In regard to risks taking in life, these are completely different than risks taken at work. I included this aspect of the discussion of risk because I wanted to get feedback from DBAs on whether or not they avoid risk in their personal lives, as they often do in their work.
At work, and in life, I have generally been very conservative. And when it comes to work, I always test carefully before making changes. But occasionally in life, I like to take a risk (not for a thrill), but because I want to challenge myself to something I have never done before. Lately, maybe because I am getting older, I find myself trying new things I would have never thought of trying before. In almost all cases, the risk has been worth the reward, and it has spiced up my life, helping me get out of the often day-to-day routine of life.
