The best to guard yourself from everything, is to guard your heart.
It seems to me that our heart is the getway of emotions. Hmmm, been reading up pretty alot on astrology and it's really true.

Pisces is so emotional, in fact, that it can tend toward depression or fatalism; the weight of the world can be too much to bear for someone so sensitive. Many Pisces turn to escapist pursuits as a result; daydreaming is one rather innocuous form of escapism.

Trouble trouble. Gotta start to think with my mind instead of my heart all the time.
