You have heard the old saying it's not personal it's business... Bullshit. It's personal and it always is and always will be. If someone doesn't want to buy something from you car or not it's because they didn't like you enough to make that forward movement with you as their guide. Pretty much all products on the market are the same or close to the same except in the line of extra premium items and if they don't want to buy yours instead of the next guys IT'S PERSONAL!
