It is very important that you must know your strength and weakness to succeed in your life. If you know your strengths then you can use them to succeed in life and if you know weaknesses then you can work on them and improve them.
You might have heard that on full moon and new moon days there are higher tides in the ocean. Every object in this world has its own energy and how importantly we can use this energy for our benefits, depends on our knowledge of our strengths and weaknesses. If we don't have enough knowledge on them then we should get guidance on that from someone who has that knowledge.
Criticism faced by Astrology
There are two types of people in the world. The first who say astrology is nothing and whatever you think and believe will happen .The second type of people will say that everything is defined from before and it is destined to happen so there is no point in knowing astrology.
Actually both are correct. Even though its in your birth chart, if you don't believe and try for it, you wont get it. If the time is not perfect then also you wont get it. But on the contrary if its not written in your birth chart and you use all strong points of your birth chart, you can achieve huge success.
You need to know what is good or bad for you then only you can take right path.
So, its not important what others say, what's important is that you need to get success in life financially and materially in every dimension of life. It's your right to know what is good for you and what you should avoid to achieve success.
