It seems that you are getting good advice.
Personally, the one time I ran myself into the ground that way I ended up turning most of my tanks into either species tanks or even specimin tanks, with only a single fish or at most, type of fish in each. This also reduced the maintainance a lot by reducing the bioload in each tank. It got down to just two community tanks which were well balanced and lacking aggression. I also ended up with fish in the rest of the tanks that were easy keepers. If you do take a break I suggest that as someone already said, you do not get rid of your tanks, just break them down and store them for a year or two while taking a rest, otherwise it is almost a given you will regret it.
