Why do we have Belief systems ?

I am writing today's blog in a very sad state of being. Little angry but mostly sad.

I am trying to understand why do people believe in astrology, horoscopes or other psychic sciences. I guess they want to believe that they have some special knowledge which would allow them to take control of their own destiny by seeing what potentially lies ahead. They want to avert danger, take advantage of good opportunities, etc. etc. I am not saying that astrologer's advice is not good. It is much better than no advice at all. Some people need reassurance in whatever form it comes. But astrologers who recommend against particular marriages or projects because of the "stars" might be providing disastrous advice. There is, sadly, no way to differentiate between the two.

I personally don't believe in them, not because they might be false or whatever. I feel we as humans need to live our lives like God wanted us to be, based on unpredictability. If all of us are trying to know the future then where does it place God? He has his ways of dealing when we try to know the future and fight with our destiny. He might say, ok so you found out tentatively that this particular thing will happen to you and got away with it, Great I will put another roadblock in your life when you were busy taking care of and celebrating your little victory.
I would think God wanted all his creations to live the life he created and fight the problems with love, empathy and compassion and face all fears and uncertainties heads on.
I guess astrology is like religion, some people believe in it and others don't. But what confuses me most is how can you base you life's decisions on external factors. Is it the coward in you who needs reassurance in the form of third party that your life will be good or is it you need a third party to blame your failures on.
My horoscope might say that a particular person might prove to be a great husband in terms of all statistics but will I ever be able to fall in love with that person? Great married life means great love, compassion and trust to make you sail through all the difficult times.
Another question which my mind is not able to fathom is if astrologers can tell you about your love life/business/health, do they know what will happen to them next few hours/months/years. Why don't they make their life predictions in such a way that they could be the richest, most successful and people with happiest personal lives. My reasoning would be how much so ever you try to manoeuvre your life but God will throw curve ball at you and then you will not know what to do? You will be yourself hurt and you will hurt all the other people on the way. So, what path is better? Trying to play hide and seek with God or just follow your heart and be mentally and physically ready when God throws lemons. As they said when Heaven throws lemons at you, make a Pink Lemonade. Yummmmmmm...Slurrppppp :)
