My son's date of bitrh is 3-12-1989,I wnted to know his carrer,& future. sutable field for him

As long as he is ambitious and has clear target, he will be successful sooner or later. As for the career development, he should work harder and have good relationships with colleagues and leaders. Then he may get a promotion though he is so young. Well, if possible, you can help him to run his own business, which would succeed.

Thank you
