I think a good way to ensure that you will be able to be revived sucessfully is to take matters into your own hands and work on improving brain preservation technology / awarness right now. For example, you could volunteer or otherwise help out the Brain Preservation Foundation (http://www.brainpreservation.org/). Or help out research into this technology directly. As we get more information about preservation and how it works (and why it doesn't), it will become more obvious what you can do personally to get a better preservation.
