@Sacman: Cynicism all the time may be logical and safe....but that is the problem. Humanity and life and all that occurs in it is not "safe" by any stretch of the word, and sitting back never wanting to be disappointed not only stunts your emotional growth, it also denies yourself the experiences that you could be enjoying much more if rather than sit back and be logical you instead just feel excited, or just go expect the best out of something, or hope that this time everything will work out good.
Waiting for failure or falling all the time sometimes breeds it to occur.
