I've learned astrology for 3 years. Before that I didn't believe in astrology. But if you want to criticise something you have to know what you criticize. This is correct aspect, isn't it?
Now I believe part of astrology. I think the radix (birth chart) is good to describe your behaviour, character, etc. But I don't believe in solar (yearly, monthly, daily) astrology, I don't believe in "questioning astrology", "medicine astrology" despite of I was tought to them.
