If you could have once special ability, what would it be?

First off my apoligies if this question has already been asked. =) But if you could have a special ability, what would you want? What would you wish for? For example; being able to time travel, or jump to any location, immortality, see the future, talk to animals, move through objects, hear people’s thoughts, abnormal strength, being able to heal yourself and others, etc. etc. =D
