Here's a simple way to have a better 2016.
Step 1: Keep a file of the good stuff you do. Maybe it's an email thanking you for the request you just completed or perhaps it's a hard copy file with written thank you notes you have received.
Step 2: When the day isn't going the way you planned or you get a tough caller, review your Yay Me! file for a reminder of your awesomeness.
Repeat as needed...
