What kind of insurance? Car/home, life, etc... I first hand saw a friend of mine start selling car/home insurance without absolutely no knowledge of the industry. It takes a lot of hard work, long hours, and tremendous patience to build up your customer base. Friends will only go so far, in fact friends will be your worst nightmare, don't rely on them, they go where it's cheapest usually and for some reason they don't feel you're qualified enough to sell the product because your new, weird, but true. Also, it depends if you are selling an exclusive product, or if you are an independent agent. Lots of questions, but don't underestimate the tiring, long hours, if you want to be successful.
