autumnleafGratitude doesn’t happen once a year. It isn’t something you practice only at home.
Exhibiting gratitude in business and at work shouldn’t be weird. The appreciation for your customers will serve you as a daily reminder for whom you are serving. It will become a habit if you internalize it.
And most of all, it will eventually show and serve your customers as a reminder on their side to why they are working with you.

Despite everything what we may not like about our job, there are always a lot of reasons to come back every day. Appreciate those. Every day.
Show it and give credit whenever you can.  Eventually, the reasons to come back will multiply, because appreciation is contagious.
