If you’re broke, in big debt, and have a great idea for a product, service or new business model, I always recommend you keep your current job and income, and do both.
It’s going to be a challenge, but that’s what entrepreneurship is all about.
You have to pay your rent, bills and eat, and that most likely won’t happen from starting a new business for a while.
But don’t be discouraged.
Let it be your incentive. Until you’re at a point you finally must be full time on your new business and can afford to take the leap, then I recommend you solve making both happen.
