The main takeaway I got was you saying that not everyone will get it, what kind of trade show was it?

It is a lot easier to sell to people who have a problem they are willing to solve, your job then is to connect your solution to their problem and help them join the dots.

Trying to get people to first pay attention, then get interested, and then get motivated to purchase, and then purchase (without calling their spouse etc) is a lot more difficult.

That is why markets often sell

1. Things people came there to buy
2. Things that they immediately want and can afford (impulse purchases, basically)
