While the advice here is good, I think it approaches the issue from the wrong angle. You can't reasonably expect to just up and change what people think or how they react. You can change what you do or how you present it. What changes is not the reaction to, and it's most certainly not the odds of, the exact thing you're currently doing succeeding.

It's the product/service/approach/target audience/etc. that needs to change. The "odds" are an output, something you can only change by altering your inputs.
