I have to agree with adzymcfadzy - it's a bit of both. Occasionally I'm feeling motivated and in a good mindset to learn, and at other times, I think of the SQL Server 2008 features that I know about, but have never had the opportunity, or the urge, to play with. Until yesterday, Powershell was in that category, and it's depressing to think how far behind the ball I am in that area.

I think it is important to realise that everyone has their own facet and skill set separate to yours, and that YOU don't need to know all the answers. Instead, know enough so that you have a general overview, but you know where best to turn to when you need to ask the questions. I think this is ultimately better for my career - knowing everything intimately is impossible, but knowing where to turn and getting results is what counts.

And it shouldn't be a feeling of insecurity. There's so much SQL work out there that the A-list SQL celebrities can't do it all themselves!
