Should I give up?
eande: You say "feedback I've got from people". People will tell you what you want to hear and often don't really know. Most important ask customers or potential customers, listen to them.And on the financial part lots of good ideas here and as usual minimize your expenses and find some income (part time, consulting) you can go a long way.You need to believe in your cause and if you listen to the successful entrepreneurs they will tell you don't give up than you know what you need to do.Set yourself specific limits now when it is time to stop (financially, emotionally), but when you agree to give up, give up fast and learn from it.
