Give people the care they deserve.
When you promise to get back to them within 3 days and later on you get to know that the work might take another 2 days, be sincere and caring enough to call them and communicate.
Give your deliverables with love and authenticity.
In a world of broken promises, keep your word. And reach on, no, before time.
We are fortunate enough to have food that is on our table because of our customers. Give them the gratitude and awesomeness they deserve (yes, even if they are no longer your customers, we owe our humanity to them. No one can take that away from us.)
People sniff honesty from a mile away. Customers buy experience, not products or services. You will be the market leader even if you charge higher than your competition because you love your customers genuinely.
