How to know when it's time to quit

The Business Opportunities Weblog has posted this set of guidelines that help you know when it is time to quit:

• None of your closest friends or relatives has invested a dime — or even expressed any interest
• The total amount you’ve been able to raise is less than $25,000
• No one wants to join you in your madness and work for free (or stock)
• No customer has been persuaded to buy your product or service
• Your intellectual property attorney said there was nothing worth patenting
• The last investor you presented your idea to asked if you were joking
• You’ve been doing this for more than three years and still can’t support yourself or the company hasn’t hit break-even

Common sense stuff, but nice to see in an easily digestible bulleted list.
