Time is running, what should I do?

I am an Indian guy, age 23, working as an IT professional.

I always have been a family and social guy, luckily/unluckily I got a good job but far away from my home town. Now my home sickness and social myself are not letting me work properly, I am ripped of metro culture and want to go back to home and spend my life there with my parents.
But main problem is that there are no jobs for my field near by my home town and in my part of earth, 24-25 is right age to marry, else all good girls will be gone.
So if I start a business, I have only 1 year of time to establish it well cos no body will give his daughter to a guy who is not settle and in case I fail to establish a good business I will be gone by money and marriage both.
and if I continue job away from home, I will be just living my life not enjoying it.

As time is running and I am becoming more puzzled day by day.

Please suggest me what should I do? incase you need any further details, please let me know.

I must say that you REALLY think at least. Many of us don't even think.
Second thing, are you missing your parents or your hometown? If you are missing your parents, then concentrate on your job first and keep in mind that the time that you wanted to give to your parents has been taken by your job and you have to compensate that in future.
Talking about your marriage, since in a year or so, you will be married, you will soon need parental support too. Parents too will be happy to live with you and your wife. So, think in this way - earn a lot, become good in your carrier, stabalize your life and get your parents near you. This is also good because soon due to older age, they will need better medical attention that will be better available in town than in a village.

Think about it !!
