I came to understand why the quality of some product or service is declining overtime in the business world after I had my own company. You will give you every best service for every client but then when the workload is too much to handle plus the payment that you get is not really worth all the time you take to perfect your service or product, you will start to lower your quality of the product or services to compensate the time taken to handle all the workload that coming to you.

Sale is never end but the standard will determine which sale sales. :) Just my humble opinion my friend! Cheers!
