When photographers talk about the rule of thirds, they say sometimes they will break the rule and still the photo will have great composition. When should I stick with the rule of thirds and when should I break it? And when I break it, what should I use instead to drive eyes to specific points in the photo?
The rule of thirds to me is a rule of thumb, a reminder not to mindless frame my subject dead centre of the frame, or else I will probably end up with static or boring images overall.
As a beginner, it's a good rule to keep in mind. Not to blindly follow, but to help encourage you to try different framing, perspectives and so forth. As an experienced photographer, you'd probably not even think about it but you'd naturally tend to frame subjects off centre to make them more interesting.
Specific situations where rule of thirds might be "broken"? I would say primarily this is where symmetry is the focus of the image:
For specific effects
The bottom line is that you are the boss and if you think it looks good then don't worry what the rest of us think!
Given that, here are some suggestions...
Placing a subject in the centre can:

This makes the viewer think about what is outside the frame, and creates a not-entirely-comfortable feeling that the image is out of balance. Usually photographers want to avoid this, but if it is what you are looking for in your work then go for it.
How to drive the eye?
The human eye:
... that's a bit of a random selection, but I hope it helps.
I agree with the comments above. It's a guideline, not a hard-and-fast rule you MUST follow. Go with what looks right to you in the viewfinder.
