I guess I just consider myself lucky to have had a great boss that pushed training into our laps. He always said you should be spending at least a couple of hours a week reading articles, learning something new.
You're fortunate in that regard, yes; but give yourself a pat on the back as well, for having the desire and willingness to learn. I see far too many people in IT - and not just DBAs - who seem all too happy to just sit on whatever knowledge they acquired years (even decades) ago. They never learn anything new, and become a drag on those who do.
How this kind of people - and their IT shops - manage to survive is a mystery to me.
