If I got a cold call from someone who asked me what my pain point is, I would hang up on him. That's because I am too busy to take time out from my day to sit and think about all the things that bug me, slow me down, cost me money, or hamper my ability to make money. There are probably a dozen things I can thing of, and if I thought about it probably 100 things. But I am not going to waste my time thinking about all this just so you can take my ideas, start a company and make a ton of money by reselling my own ideas back to me and not offer me a dime in compensation.

And that's probably how a lot of business owners would think. So the problem with your approach is that you are missing the one critical element for success in any field -- you must have good relationships first before you call anyone up.

Let me say that another way: Success in business is almost entirely based on personal relationships! If you don't have personal relationships with people you want to do business, you simply will not get anywhere.

So before you do this, you should either develop personal relationships within the niche you are contemplating, or decide your niche will be within the personal relationships you already have. Which is easier? Obviously, the latter.

So start with the business people you currently know. It could be the person who cuts your own and owns his own hair salon. It could be the immigrants who run the dry cleaner that you always take your clothes to each week. It could be your neighbor who is a lawyer. You catch the drift.

Once you have a relationship, they are much more willing to help you out, and you can continue the conversation over time. They likely won't be able to think of anything immediately, so just encourage them to write down anything that comes to their mind as they go about doing their job.

It will also help if you take them out for coffee, and be sure to pick up the costs. they are going YOU a favor, so you should at least return the favor.
