I think every one should give it a try. If you don't try you can't say if u r good enough and have all the skills to become entrepreneur. So have a faith in youerself and give your best shot to it. you can do it whenever you think time is right for you , Be it just after MBa or after working for some one else.
so go and try it.
I am working on the idea ifany one intrested to Invets let me know
