Ha! I hope you all are not assuming that I'm seeking advice

. I've already been there, done that

.
1. As Mayur said, in most of the cases its the pressure from family or responsibilities that prevents most of the wannabe entrepreneurs from quitting the job.
2. As Differential said, yes its difficult to come out of comfort zone. The feeling that there won't be any paycheck at the end of the month, gets all the guts out of most of the people.
In my opinion - lot of people have lot of money to return to the banks [ the EMIs, I'm talking about]. That's one reason I've noticed, prevents wannabe entrepreneurs from quitting their jobs.
All said, most of the startups do not have a steady revenue source at the beginning.
One solution I propose is to pile up enough money to take care of your expenses for 1 year and giving your dreams a go.
What say?
