How do you reconcile the “but I want you to buy my product even though I am not interested in yours” attitude? Life is always a little quid pro quo, or “something for something,” and we can’t pretend that it isn't.
It is a courtesy to both sides that you don’t waste time dealing with something you absolutely will never buy or use. But if there is some curiosity there, it is worth the meeting. If you want to “sell” yourself, try to offer something of yourself that isn't a sales pitch. Sometimes the best connections come when you aren't even trying.
When you identify a company/individual that could benefit from what you have to offer, take a moment to determine what they bring to the table that is of interest to you. The biggest companies are just looking for numbers but hopefully, you are looking for business relationships. That means getting to know your potential customers; really knowing them.
Let’s face it – the company that makes your favourite cereal doesn't care about you as an individual. Sure they care about your opinion enough to ensure that it results in sales, but they haven’t found out much more about you than that you eat their cereal.
Don’t be that company. Large or small, if you are selling to someone that has something to sell as well, really try to mine the “something for something” approach. You will have a longer-lasting business relationship than a one-time purchase. And that is why you are in the game.
