Every rip-off artist will eventually end in destruction. Constant mental fear of getting caught. However, once it's spent the rip-off artist must think of a new game. The honest dealer doesn't have this problem and keeps money coming in over a longer period of time. That's why life becomes a circle of doom for these foolish and greedy people.
Money is never a lasting thing.
However, a good reputation and pride in your product or service cannot be purchased. Word will generate quickly of your business simply because of your honesty and your mailbox will be stuffed with orders, inquiries and letters from people with whom you will make lasting friendships. It's so simple to be honest. It takes a lot less energy and brings in MORE money in the long run.
