You need to value the new venture. Have a business case in place to see if it is worth pursuing. That is, a financial valuation.

My one advice is, do NOT self-fund. If your case is strong enough you can find angel investors and venture capital funding.

And yes, agree with others do not drop out. Don't give your business idea but make sure you have a strong case first.

Let me give one example. A student in Hungary once hired me to do a valuation and business plan for his idea of en eco-friendly school in Estonia. What seemed to be a good idea in his view showed a negative 1.5M Euro after three years of operation after I did his financials.
