Patterns and always having to look on the bright side. On the one hand you can be shizophrenic and get all this confidence because it's like, "Oh, I've been here before" and you can be all smug about what's going to happen.
On the other hand, you always have to either break yourself away from that faith at some point and tell yourself, "No, I've learnt from my mistakes and have improved" in which case you lose consistency with the pattern you were matching with in the first place, or you have to compromise and look further ahead, getting all caught up too.
Oh, the realizations
