Admittedly, I'm a fan of horoscopes, fortune telling and other related stuff connected to knowing the future. I know it's immoral in the eyes of the Christian milieu, however, I think it wouldn't hurt if somehow you put it in a perspective where you do not taint your faith in Him. My analogy however is that if you get to know aspects where you can change, add and alter for the sake of focusing into getting something or achieving something, it helps as it increases your focus.
My stand on this science (or art) is eclectic by nature. I'm a big fan of "The Secret" by Rhonda Byrne and at the same time, I believe in Feng Shui concepts. Feng Shui is an oriental wisdom geared towards putting "balance" in your surroundings to acquire energy and cosmic interventions. Putting this two ideology I think masters your chances and increases positive energies towards your common goal.
The universe conspires to what we think, so therefore, if you have that thinking that this something will work for you, then it'll surely do.
