First, Opening your own business in the big city is a big step, so I think you should be recognised and congratulated on your efforts.

2ndly, I imagine by this time you've already found ways to increase your sales performance.  Now, the problem that I'm seeing here are the attitudes in that using NLP and subliminal suggestions can only be bad.  That depends on the personal value system and intentions of the person utilising these tools, doesn't it?

Everyday, we can see that ethics and morals are out the window for the big advertisers using Tavistock Marketing tactics.  Big pharma drug commercials and Fox News "interviews" are always using NLP and subliminal suggestions in the name of instant gratification and control of the audience.  Most people only see these little "signs" on the subconscious level.  This sort of mind control is to the detriment of society which is why some people say it's bad - while others just can't "see" it.

On the other hand, how's your moral compass doing?  Are you selling motorcycles in the name greed?  Or do you want to provide riding pleasure and power for some people?  For others, you might want to provide something practical that saves gas and is compact, so is easy to find parking.

Are you truely passionate about motorcycles and their benefits or are you only passionate about the money to be gained from their sale?

I imagine that you are truely passionate about motorcycles and their benefits including electric motorcycles.  (A lot of people are thinking green these days while others just don't like the noise.)  

I'm willing to bet that because you're here at this forum, that you're a good person who likes to motivate people wisely and for their own good - like everyone else here.  I'm also betting that you're not a satanist having people sign away their souls for a bit of pleasure and instant gratification.

What you might want to do is look up "The Convincer Strategy MetaProgram" by David Barron; it's an ebook floating around on the web.  Here's an excerpt:

"A MetaProgram is a way that people sort information. People will only respond to your attempts to influence (read SELL) if the information
you tell them fits their MetaProgram. There are a lot of MetaProgram and all are valuable to learn. The one that most sales people can easily
use once they learn it is The Convincer Strategy MetaProgram..."

If you can't find the ebook, then I can find a way to give you a copy.  You should also look up Keys to Power Persuasion by Alan Tutt which can be found at my site.  This course contains all kinds of sales strategies that are used in the world today (mainly Tavistock strategies) that can be used personally as well as professionally.  The keys help you determine personality dimensions of your sales prospects by listening to their answers of a few simple questions, then form a rapport according those dimensions.  And you know, having that rapport is most important for gaining a permanent customer.

Of course, this information is not just for Han; it's for every good person reading this.  Human society is in trouble because of so much bad influence.  When we get enough good people using the same tools, we can "shock the monkey" back into acting upon emotions of love rather than fear.  When we do that, we regain our humanity.
