Barry left out one suggestion I would make. try and find a mentor! If there are other DBA's in your company, go to one that you feel comfortable with and ask that person to be your mentor. You'd be shocked at how many people would say yes. Having a mentor can help alot when it comes to self study. As a life long student of all things IT, mentors in my career have been very encouraging and educational to me. Find one. If there is not one at your company, find on online.
