    One of my client Motivated me to follow these golden guidelines. 1. Keep in mind that most of your clients want to feel appreciated. 2. Always treat your clients like you want to be treated. 3. The most successful entrepreneurs are those who know how to treat clients. 4. Every client is a potential referral - always remember that. 5. Continue to work on your business savvy and NEVER let money be your motivation (driver). 6. This creates a "lack mentality" and you will always have to scrap for money. 7. Prosperity comes from giving your BEST every single time (even when you don't want to).  less
