One of the ways you can love the people in your life and grow your relationships is by affirming the good things they do.
Today, tell a person something specific you appreciate about what they've done recently.
A meaningful way you can do this is by writing it down and leaving a note on his or her desk. You can put it in the mail. You can make a phone call or send a text message. The medium in this case is less important than the message.
A few examples:
"I really appreciate the way you cleaned up the meeting space after everyone had filtered out this morning. It's obvious you care more about others than you do about yourself."
"I was thinking about our conversation earlier and wanted to tell you how much I appreciate how intentional you were with your questions. You do a great job putting curiosity into the service of others."
"Your presentation today obviously took a lot of preparation. Thanks for putting in the work to honor your audience's time and deliver an excellent speech."
To become a more encouraging person simply requires exercising your encouragement muscles more often. You do this by opening your eyes to the strengths of others and boldly telling them what you see--one note/conversation/phone call/email at a time.
