I would love to be able to have that look-over-the-shoulder experience for DBA tasks the way you were able to watch the other roofer. I guess SQLShare videos and other SQL videos give some of that experience, but a mentor is what I really need. And not just for technical tasks but also for soft skill and other interpersonal tasks as well.
At the moment I don't even really see the equivalent of the other hypothetical DBA doing things in half the time - I just have a vague sense that there has to be a better way and that the volume and variety of different things to do are overwhelming. It would be extremely helpful to have a DBA mentor video series for things like that, in particular taking a look at a given SQL environment and DBA work process and recommending ways to do things better. You could even have someone in the role of the DBA that needs help, so the two of them can talk it out for instructive purposes. I think that would be a great series.
