consider this fact: the planet consists of water at 70%.
the water on earth moves according to the movements of the planets, especially the moon.
then think about our body, which consists of water at 70% too.
if this happens with the other three elements - air/earth/fire - then there must be some connection.
personally i believe in the characteristics of each sign - not particularly in everyday predictions though.
p.s. listen to what your heart tells you - it always has the correct answer which only applies to you!
