Dear Madhuma,
If You want to start your own business. Please consider :
1. What would be source of funds ? You have some saving amounts or borrowings from banks/market (Do you have any property for mortgage?) or Family Funds?
2. Do You Have sound experience in that field or You will depend on others?
3. What would be pay back period i.e. when you will start earning profit?
4. Can you maintain house hold expenses for at least six months without any income in hand?
5. Will you get support from your family as in initial months it would be very hard to spare time with them, you have to focus only on your business? Is your family emotionally matured ?
6. You want to start your business because you have no job in hand or you are really enthusiastic about your venture ?
If You have to arrange funds at your own and you are not technically sound and depend on others for know-how, Better Be in job for some more time. Make a proper plan, research, save money and then after two or three years again review the position and take rational decision.
This is my personal opinion, based on experience.
May Baba Sai Guide You and help you to find right path in the life !
om sri sai ram !
