Salman,
You are better suited to work for someone else than to open your own business. You experience at the moment what is called Saturn Return, a time when transiting Saturn which at your birth was in Sagittarius, has come back to the same spot as it was 30 years ago. Now you feel you want to take a new direction in life. Saturn is the planet which helps us with its influence to get things done right.
And your natal Saturn has two trines (auspicious aspects). One is with your natal Venus, so in matters of love you do the right thing. Second trine is with your natal Moon, so your feelings won't play tricks on you, and when things of the heart are involved, you always do the right thing. You could marry in the year of the Earth Dog 2018. Try to find a woman born in 1994 (in the month of Cancer or Scorpio), as she will be your best match. You are suited to work in industrial or religious circles or as a public figure. Do not smoke, and keep away from cold or air pollution , as your lungs aren't strong. You are well-organized. You work hard, and manage others to work alongside you.
You like what is most practical. You appreciate things that are durable and long-lasting. You love integrity, philosophy, and law. Good luck to you.

Hello sir. I live in Pakistan . So job situation is very bad for jobs.nobody is willing to pay good salary.that is why I was thinking about doing business of my own . Will opening my own business be bad for me?

It will be OK if you open your own business in the year of the Rooster(in other words after the 28th of January 2017). Good luck to you.

Thank you
