If the OP can take this on without BORROWING MONEY, DO IT.
Jobs come and go, TIME ONLY GOES.
I will say that Im a risk taker, and Ive learned "risk" without debt can really pay off. Risk with "debt" can turn into a real nightmare.
Theres no reason not to be confident about building a business, these oppoturnites don come around very often. Jobs will be around as long as we have a econmomy .
