Astrology can give you a more objective view of what you’re dealing with, it’s worse when you turn it into self-fulfilling prophecy. It’s observations and opinions based on those observations, as far as interpretation goes. Some people blame all of their problems on Saturn and everything good on Jupiter. Speaking from my own chart, especially vedic where my Saturn is functionally benefic and Jupiter malefic, what things are, what’s “good,” what’s “bad” depends a lot on context. Like all things, it’s a useful tool if you use it wisely. It won’t condemn you to a horrible life, but a wonderful life isn’t necessarily given either even if the chart is wonderful. You always have choice, just your choices will be different from someone else’s and different decisions will be more impactful for you rather than others.
It’s also great to understand the retrograde cycles, what times are good for certain things, etc. Also helps to know, in a general sense, nothing is forever here. All things change, sometimes slowly (Saturn), sometimes quickly. And you change, too, and astrology is just another way to see it.
Astrology works well with my mind, things like tarot not so much. If you find that astrology just doesn’t do it for you, then maybe you don’t need it. Good to know that what the general influences on the world at large are, though.
