The most effective cure seems to be extreme budget limitations or life catastrophes, neither of which are ideal... just remember the dangers of letting it run wild and remedy the urge for more tanks with more research about one specific tank instead. Note the stress on this last part. After reading through your other recent threads, I feel this warning is necessary.
Take one tank in mind, plan and research as much as possible, and see it through to success for a year or longer before starting another.
I have been trying to keep patience in the reefing hobby to avoid failures of my past. When I was about 12 years old, I got introduced to keeping reptiles, specifically bearded dragons. Over the next few years, I very quickly expanded my interests into many different reptiles/amphibians and soon had tanks of geckoes, armadillo lizards, tree frogs, tiger salamanders, iguanas, toads, maybe I am forgetting some? Most of these ended in catastrophe for the occupants due to my lack of adequate species-specific research as well as too little time for such a wide array of maintenance and care needs... now I limit my passion within reasonable bounds that I can actually maintain so as not to selfishly cause the death of my pet animals.
Most died due to lack of understanding on my part or proper research, some died because I was too cheap for proper care, some died due to lack of emergency measures, some died due to neglect when my time was spent on other interests, some died when I was away from home at college and my family knew even less than I did about their care... there are just so many ways that we can inappropriately keep (and likely lose) animals. I don't want the mistakes of my childhood to ever occur again.
