Dear Dharani
What is your goal. Please decide yourself about your industry of preference in which you would like to go ahead in your career.
If you are prefering to go in Manufacturing Industry, then you have selected the correct path. Please gain thorough knowledge about your family business, assist your father in all his business matters, learn the business tactics and try to improve the business in higher level, so that you can give more employment to the society where you have established your industry.
Further you can do some HR Related course also, so that you can have complete control on Accounts, Marketing and HR Department of your family run business.
Wish you all the success.
3rd November 2012 From India, Kumbakonam
