too much continuation betting

I haven't discussed it much, but I joined pokerxfactor in February. I think it has helped with my S&G bubble strategy. So far, I've only watched Sheets' beginner video on ICM and bubble strategy in S&Gs and I've half way through a Bax video of a $50 MTT. One thing I see Bax not doing is much continuation betting. Perhaps his stack is deeper so he sees less of a need. And maybe that's one thing I need to learn from - when it's appopriate to continuation bet and when it's not. With deep stacks I'm too aggressive still. I need to slow down. Once I continuation bet, I build a pot and then it becomes more juicy - but I should be able to get away from it after I raise with AQ and the flop comes ten high.
