I think i lost my question. at lease half of it. my question is can you explain why the horoscopes

Do not match the people withe the same animal that is their birth sign. For example my birth sign is tiger, and i am suppose to be leader or have power , and all other good qualities , but i do not have a leadership quality, nor i feel powerful , and i don,t like attention.
And i was reading my son,s sign which is snake, it says he is calm in the outside , which is not true, he is always angry , and very loud , And he has financial problem all the time. He does things without thinking about the result .And is not wise . And does not take responsibility for his action, and always blame it on some one. And does not listen to sound advise , and is very controlling .And refused to go to college , and the one he started , he dropped out, and spent the money , for his ever day life , and now have a lot of debt
And i have worry about him all the time. Because his father does not care. And he has 2 kids. But he is good father, he can be a little softer , and easy going. of course he is child of divorce parents. with a very strict father. Which did not want to have child. And now he has disowned him . Sorry telling you all this private stuff. I really don,t know what to do about him. If i don,t support him either , the children will suffer. And he will end up in the streets. Your insight and advice are very welcome.
