Job or self Business -- which will be be better for me.

Namaste,
I am an Architect living in Dubai (UAE) for the past 10 years. I recently changed my job (after 8 years) and was then chucked out from the new company and I am jobless now. I am searching eagerly for a new Job. Alternatively I am thinking to start my own business (Architectural Interior design business) but which will require some capital. But spending so much and then not getting the benefits is where I am hesitant to start my own setup. I am going through a very uncertain phase -- should I wait for a Job opening or go for a my own setup. My DOB is 26th July 1972, time 18:45 hrs place, delhi (India). Kindly advise.
